Archaeologist and adventurer Indiana Jones is hired by the US government to find the Ark of the Covenant before the Nazis.

Marion: You're not the man I knew ten years ago.
Indiana: It's not the years, honey, it's the mileage.
Indiana: You want to talk to God? Let's go see him together, I've got nothing better to do.
Belloq: What a fitting end to your life's pursuits. You're about to become a permanent addition to this archaeological find. Who knows? In a thousand years, even you may be worth something.
Indiana: Ha ha ha ha.
[under his breath]
Indiana: Son of a bitch.
Indiana: Do we need the monkey?
Marion: I'm surprised at you. Talking that way about our baby. He's got your looks, too.
Indiana: And your brains.
[Upon opening the Well of the Souls and peering down]
Sallah: Indy, why does the floor move?
Indiana: Give me your torch.
[Indy takes the torch and drops it in]
Indiana: Snakes. Why'd it have to be snakes?
Sallah: Asps... very dangerous. You go first.
Indiana: [Indiana is being strangled against the bar. He calmly looks up at Marion] Whiskey
[Marion hands him the whiskey bottle and he smashes it over his assailant's head]
Indiana: There's a big snake in the plane, Jock!
Jock: Oh, that's just my pet snake Reggie.
Indiana: I hate snakes, Jock! I hate 'em!
Jock: Come on! Show a little backbone, will ya!
Indiana: Meet me at Omar's. Be ready for me. I'm going after that truck.
Sallah: How?
Indiana: I don't know, I'm making this up as I go!
[Marion is being kidnapped]
Marion: You can't do this to me, I'm an AMERICAN.
Brody: Marion's the least of your worries right now, believe me, Indy.
Indiana: What do you mean?
Brody: Well, I mean that for nearly three thousand years man has been searching for the lost ark. It's not something to be taken lightly. No one knows its secrets. It's like nothing you've ever gone after before.
Indiana: [laughing] Oh, Marcus. What are you trying to do, scare me? You sound like my mother. We've known each other for a long time. I don't believe in magic, a lot of superstitious hocus pocus. I'm going after a find of incredible historical significance, you're talking about the boogie man. Besides, you know what a cautious fellow I am.
[throws his gun into his suitcase]
[as the Nazis are opening the Ark]
Indiana: Marion, don't look at it. Shut your eyes, Marion. Don't look at it, no matter what happens!
Indiana: I can only say I'm sorry so many times.
Marion: Well, say it again anyway!
Indiana: Sorry.
Maj. Eaton: [sees a picture of the Ark with rays of power coming out of it] Good God!
Brody: Yes, that's what the Hebrews thought.
Indiana: Here, take this,
[hands Marion a torch]
Indiana: Wave it at anything that slithers.
Marion: The whole place is slitherin'!
Sallah: Indy, there is something that troubles me.
Indiana: What is it?
Sallah: The Ark. If it is there, at Tanis, then it is something that man was not meant to disturb. Death has always surrounded it. It is not of this earth.
Dietrich: Dr. Jones, surely you don't think you can escape from this island?
Indiana: That depends on how reasonable we're all willing to be. All I want is the girl.
Dietrich: And if we refuse?
Indiana: Then your Führer has no prize.
[Indiana falls asleep while kissing her]
Marion: We never seem to get a break, do we?
Brody: However, an Egyptian pharaoh...
Indiana: Shishak.
Brody: ...yes, invaded the city of Jerusalem round about 980 B.C., and he may have take the Ark back to the city of Tanis and hidden it in a secret chamber called The Well of Souls.
Major Eaton: [skeptically] Secret chamber?
Brody: However, about a year after the pharaoh had returned to Egypt, the city of Tanis was consumed by the desert in a sand storm which lasted a whole year. Wiped clean by the wrath of God.
Major Eaton: [turns slowly toward Col. Musgrove] Uh... huh.
Colonel Musgrove: Obviously, we've come to the right men. Now you seem to know, uh, all about this Tanis, then.
Indiana: No, no, not really. Ravenwood is the real expert. Abner did the first serious work on Tanis. Collected some of its relics. It was his obsession, really. But he never found the city.
Major Eaton: Frankly, we're somewhat suspicious of Mr. Ravenwood, an American being mentioned so prominently in a secret Nazi cable.
Brody: Oh, rubbish. Ravenwood's no Nazi.
Colonel Musgrove: Well, what do the Nazis want him for then?
Indiana: Well, obviously, the Nazis are looking for the headpiece to Staff of Ra and they think Abner's got it.
Major Eaton: What exactly is a headpiece to the Staff of Ra?
Indiana: Well, the staff is just a stick. I don't know, about this big. Nobody really knows for sure how high. And it's...
[turns blackboard to blank side]
Indiana: it's, uh... it's capped with an elaborate headpiece in the shape of the sun with a crystal in the center. And what you did was, you take the staff to a special room in Tanis, a map room with a miniature of the city all laid out on the floor. And if you put the staff in a certain place at a certain time of day, the sun shone through here and made beam that came down on the floor here... and gave you the exact location of the Well of the Souls.
Colonel Musgrove: Where the Ark of the Covenant was kept, right?.
Indiana: That's exactly what the Nazis are looking for.
Major Eaton: Now what does this Ark look like?
Indiana: Uh... there's a picture of it right here.
[opens a book on the table]
Indiana: That's it.
[they all look at an illustration of the Hebrews devastating their enemy with the Ark]
Major Eaton: Good God!
Brody: Yes, that's just what the Hebrews thought.
Colonel Musgrove: [pointing to a beam of light] Uh, now what's that supposed to be coming out of there?
Indiana: Lightning. Fire. Power of God or something.
Major Eaton: I'm beginning to understand Hitler's interest in this.
Brody: Oh, yes. The Bible speaks of the Ark leveling mountains and laying waste to entire regions. An army which carries the Ark before it... is invincible.
[Discussing the fate of the Ark]
Maj. Eaton: We have top men working on it right now.
Indiana: Who?
Maj. Eaton: Top... men.
[talking about Marion's late father]
Marion: He said you were a bum.
Indiana: Aw, he's being generous.
Marion: The most gifted bum he ever trained. You know, he loved you like a son... took a hell of a lot for you to alienate him.
Indiana: Not much... just you.
[Indy meets Belloq in a crowded bar]
Indiana: Belloq.
Belloq: Good afternoon, Doctor Jones.
Indiana: I oughta kill you right now.
Belloq: Not a very private place for a murder.
Belloq: All your life has been spent in pursuit of archaeological relics. Inside the Ark are treasures beyond your wildest aspirations. You want to see it opened as well as I. Indiana, we are simply passing through history. This, this *is* history.
Belloq: Dr. Jones. Again we see there is nothing you can possess which I cannot take away.
Belloq: You and I are very much alike. Archeology is our religion, yet we have both fallen from the pure faith. Our methods have not differed as much as you pretend. I am but a shadowy reflection of you. It would take only a nudge to make you like me. To push you out of the light.
Indiana: Now you're getting nasty.
Sallah: Indy, you have no time. If you still want the ark, it is being loaded onto a truck for Cairo.
Indiana: Truck? What truck?
Satipo: Let us hurry. There is nothing to fear here.
Indiana: That's what scares me.
Indiana: Stay here.
Satipo: [shrugs] If you insist, señor.
[Indiana needs his bullwhip to swing across a chasm]
Indiana: Give me the whip.
Satipo: Throw me the idol. No time to argue! Throw me idol, I'll throw you the whip!
Indiana: [throws the idol] Give me the whip!
Satipo: Adiós, señor.
Katanga: Jones is dead. I killed him. He was of no use to us. This girl, however, has certain value where we're headed. She'll bring a very fine price. Herr Colonel - that cargo you've taken - if it's your goal, go in peace with it, but leave us the girl. It will reduce our loss on this trip.
Dietrich: Savage! You are not in a position to ask for anything. We will take what we wish, and then decide whether or not to blow your ship from the water.
Indiana: I'm goin' after that truck.
Sallah: How?
Indiana: I don't know, I'm makin' this up as I go.
Toht: Good evening, Fraulein.
Marion: The bar's closed.
Toht: We are... hehe... not thirsty.
Indiana: Hello, Marion.
Marion: Indiana Jones. I always knew some day you'd come walking back through my door. I never doubted that. Something made it inevitable. So, what are you doing here in Nepal?
Indiana: I need one of the pieces your father collected.
[Marion surprises him with a right cross to the jaw]
Marion: I've learned to hate you in the last ten years!
Indiana: I never meant to hurt you.
Marion: I was a child. I was in love. It was wrong and you knew it!
Indiana: You knew what you were doing.
Marion: Now I do. This is my place. Get out!
[Marion removes heavy robe to reveal satin negligèe]
Indiana: Where'd you get that?
Marion: From him.
Indiana: Who 'him'?
Marion: Katanga. I got a feeling I'm not the first woman to travel with these pirates.
1st Mechanic: [to Indy, in German] Hey, thin man! Come here! Come here! Come here! Come on, fight! Boy, come down! Down now!
Brody: The Bible speaks of the Ark leveling mountains and laying waste in entire regions. An Army that carries the Ark before it... is invincible.
Major Eaton: Doctor Jones, we've heard a lot about you.
Indiana: Have you?
Major Eaton: Professor of Archeology, expert on the occult, and how does one say it... obtainer of rare antiquities.
Indiana: That's one way of saying it. Why don't you sit down, you'll be more comfortable.
Colonel Musgrove: Yes, you're a man of many talents.
Major Eaton: Now, you studied under Professor Ravenwood at the University of Chicago.
Indiana: Yes, I did.
Major Eaton: You have no idea of his present whereabouts?
Indiana: Only rumors, really. Somewhere in Asia, I think. I haven't really spoken to him in ten years. We were friends once, but we had a bit of a falling out, I'm afraid.
Colonel Musgrove: Now, Doctor Jones, you must understand that this is all completely confidential.
Indiana: I understand.
Colonel Musgrove: Yesterday afternoon, our European section intercepted a German communique that was sent from Cairo to Berlin.
Major Eaton: You see, for the last two years, the Nazis have had teams of archaeologists running around the world looking for all sorts of religious artifacts. Hitler's a nut on the subject. He's crazy. He's obsessed with the occult. And right now, apparently, there is some kind of German archaeological dig going on in the desert outside Cairo.
Colonel Musgrove: Now, we have some information here, but we can't make anything out of it and maybe you can. "Tanis development proceeding. Acquire headpiece, Staff of Ra, Abner Ravenwood, US."
Indiana: The Nazis have discovered Tanis!
Major Eaton: Now just what does that mean to you... 'Tanis'?
Indiana: Tanis is one of the possible resting places of the Lost Ark.
Colonel Musgrove: The Lost Ark?
Indiana: Yeah, the Ark of the Covenant. The chest the Hebrews used to carry the Ten Commandments around in.
Major Eaton: Alright now, what do you mean the Ten Commandments, you're talking about THE Ten Commandments?
Indiana: Yes, the actual Ten Commandments. The original stone tablets that Moses brought down out of Mount Horeb and smashed, if you believe in that sort of thing. Didn't you guys ever go to Sunday School? Look, the Hebrews took the broken pieces and put them into the Ark. When they settled in Canaan, they put the Ark in a place called The Temple of Solomon, where it stayed for many years, till all of a sudden... whoosh, it was gone.
Major Eaton: Where?
Indiana: Nobody knows where or when.
[looking at an old picture of the Ark]
Colonel Musgrove: Now, what's that supposed to be coming out of there?
Indiana: Lightning. Fire. The power of God or something.
Major Eaton: I'm beginning to understand Hitler's interest in this.
Belloq: Please, sit down before you fall down.
Marion: Well, Jones, at least you haven't forgotten how to show a lady a good time.
Indiana: Boy, you're something!
Marion: Yeah? I'll tell you what; Until I get back my five thousand dollars, you're gonna get more than you bargained for. I'm your goddamn partner!
Sallah: [to Indy] Asps... very dangerous. You go first.
Belloq: How odd that it should end this way for us after so many stimulating encounters. I almost regret it. Where shall I find a new adversary so close to my own level?
Indiana: Try the local sewer.
[Marion and Belloq are both very drunk]
Marion: [laughs] What is this stuff, Rene?
Belloq: [laughing as well] I grew up on this. It's my family label.
[Marion falls to the ground laughing then calmly and quickly pulls out the knife she was concealing and points it at Belloq threateningly, who bursts out laughing in response]
Marion: [laughs] We-he-he-ell I have to be going now, Rene.
Belloq: [flicking his hand and laughing] Ta-ta.
Marion: [walking off] I like you, Rene, very much. Perhaps we'll meet again under better circumstances.
Sallah: [catches date and points to dead monkey] Bad dates.
[Toht prepares to torture Marion with a hot poker]
Marion: Wait, wait! I can be reasonable!
Toht: That time has passed.
Marion: You don't need that. I'll tell you everything!
Toht: Yes, I know you will.
Indiana: The Ark of the Covenant, the chest that the Hebrews used to carry around the Ten Commandments.
Major Eaton: What, you mean THE Ten Commandments?
Indiana: Yes, the actual Ten Commandments, the original stone tablets that Moses brought down from Mt. Horeb and smashed, if you believe in that sort of thing...
[the officers stare at him blankly]
Indiana: Didn't any of you guys ever go to Sunday school?
Marion: What do you want?
Toht: Ah, the same thing your friend Dr. Jones wanted. Surely he mentioned there would be other interested parties?
Marion: Must have slipped his mind.
Toht: The man is nefarious. I hope for your sake that he has not yet acquired it.
Marion: Why, are you willing to offer more?
Toht: Oh, almost certainly. Do you still have it?
Marion: [blows smoke in his face] No.
Toht: Your fire is dying... here, why don't you tell me where the piece is right now?
Marion: Listen, Herr Mac, I don't know what kind of people you're used to dealing with, but nobody tells me what to do in my place.
Toht: Fräulein Ravenwood, let me show you what I am used to...
Messenger Pirate: [searching for Jones after the Germans board the U-boat] I can't find Mr. Jones, Captain. I've looked everywhere.
Katanga: He has to be here somewhere. Look again.
Messenger Pirate: [notices Indy climbing aboard the U-Boat] I found him.
Katanga: Where?
Messenger Pirate: [pointing to the U-Boat] There!
Toht: Now... what shall we talk about?
[Looking over the destruction of the airfield]
Dietrich: Get the Ark away from this place immediately! Have it put on the truck! We will fly it out of Cairo! And Gobler, I want plenty of protection!
Gobler: Jawohl, Herr Ob...
[Gobler is interrupted midsentence by an explosion]
Belloq: [to himself] Jones!
Marion: [Mistaking Indy's whip for a snake hanging at his side, putting a torch to it] Indy!
Indiana: Ahh! Jesus!
Indiana: Too bad the Hovitos don't know you the way I do, Belloq.
Belloq: Yes, too bad. You could warn them... if only you spoke Hovitos!
Omar: This were the old way, this says "six Kadan height - "
Indiana: About seventy-two inches.
Omar: Wait!
[turns medallion over]
Omar: "And take back one Kadan, to honor the Hebrew God whose ark this is."
Belloq: The girl was mine!
Dietrich: She's of no use to us. Only your mission for the Führer matters.
Dietrich: Doctor Jones, surely you don't think you can escape from this island?
Indiana: That depends on how reasonable we're all willing to be. All I want is the girl.
Dietrich: [looks at Belloq. Belloq shakes his head] And if we refuse?
Indiana: Then your Führer has no prize.
[the old man reveals writing on the back of the medallion, which states that part of the staff must be removed]
Indiana: Balloq's medallion only had writing on one side? You sure about that?
Sallah: Positive!
Indiana: Balloq's staff is too long.
Indiana, Sallah: They're digging in the wrong place!
[Belloq and the Nazis are walking and arguing]
Belloq: I told you not to be premature in your communique to Berlin. Archeology is not an exact science. It does not deal in time schedules!
Dietrich: The Fuhrer is not a patient man. He demands constant reports. You led me to believe...
Belloq: [interrupting him] Nothing! I made no promises! I merely said it looked very favorable. Besides, with the information in our possession, my calculations were correct.
Indiana: This site also demonstrates one of the great dangers of archaeology; not to life and limb, although that does sometimes take place. I'm talking about folklore.
Indiana: I'm gonna blow up the Ark, Rene.
Belloq: Your persistence surprises even me. You're going to give mercenaries a bad name.
[first lines]
Satipo: [picking up poison dart] The Hovitos are near. The poison is still fresh, three days. They're following us.
Barranca: If they knew we were here, they would've killed us already.
Belloq: It's a transmitter, a radio for speaking to God.
Sallah: Oh, my friends! I'm so pleased you're not dead!
Indiana: I knew the Germans had hired you, Sallah. You're the best digger in Egypt.
Sallah: My services are entirely inconsequential to them. They hired or shanghaied every digger in Cairo. The excavation is enormous. They hire only strong backs and they pay pennies for them. It's as if the pharaohs have returned.
Belloq: Next time, Indiana Jones, it will take more than children to save you.
Toht: Shoot them. Shoot them both.
Indiana: Take this...
[hands torch to Marion]
Indiana: Wave it at anything that slithers.
[Katanga meets Indy, who is dirty and injured from the truck chase]
Katanga: Mr. Jones! I've heard a lot about you, sir. Your appearance is exactly the way I imagined.
[last lines]
Marion: Hey, what happened? You don't look very happy.
Indiana: Fools. Bureaucratic fools!
Marion: What'd they say?
Indiana: They don't know what they've got there.
Marion: Well, I know what I've got here. Come on. I'll buy you a drink. You know, a drink?
Belloq: So once again, Jones, what was briefly yours is now mine.
Indiana: [Indy's first lines] This is it... This is where Forrestal cashed in.
Satipo: A friend of yours?
Indiana: A competitor... he was good. He was very good.
Belloq: Look at this. It's worthless - ten dollars from a vendor in the street. But I take it, I bury it in the sand for a thousand years, it becomes priceless. Like the Ark.
Indiana: [to Satipo] Adios, Satipo...
[Army Intelligence officer describing Indiana Jones]
Major Eaton: Professor of archeology, expert on the occult, and how does one say it? Obtainer of rare antiquities.
[Belloq and the Nazis are walking and talking some more]
Belloq: Who knows. Perhaps the Ark is still waiting in some antechamber for us to discover. Perhaps there's some vital bit of evidence which eludes us. Perhaps...
Gobler: [interrupting him] Perhaps the girl can help us.
Dietrich: My feeling exactly. She was in possession of the original piece for years. She may know much if... properly motivated.
Belloq: I tell you the girl knows nothing.
Dietrich: I am surprised to find you squeamish. That is not your reputation. Anyway, it needn't concern you. I have the perfect man for this kind of work.
[Toht approaches]
Toht: Heil Hitler.
Toht: We meet again, Fraulein. You Americans, you're all the same. Always overdressing for the wrong occasions.
