Armed with a super-suit with the astonishing ability to shrink in scale but increase in strength, cat burglar Scott Lang must embrace his inner hero and help his mentor, Dr. Hank Pym, plan and pull off a heist that will save the world.

Scott Lang: My days of breaking into places and stealing shit are over! What do you need me to do?
Hank Pym: ...I want you to break into a place and steal some shit.
Scott Lang: ...makes sense.
[trailer only]
Scott Lang: [Surrounded by police] Wait I didn't steal anything! I was returning something I stole!
[from trailer]
Hank Pym: Scott, I need you to be the Ant-Man.
Scott Lang: One question... Is it too late to change the name?
Scott Lang: I think we should call the Avengers.
Yellowjacket: I am going to disintegrate you!
Siri: Playing Disintegration by The Cure.
Hank Pym: This is not some cute tech like the Iron Man suit!
[Scott hurls himself into a door]
Hank Pym: We're doomed.
[from trailer]
Hank Pym: [to Scott] Second chances don't come around all that often. I suggest you take a really close look at it. This is your chance to earn that look in your daughter's eyes, to become the hero that she already thinks you are.
Yellowjacket: You think you can stop the future? You're just a thief!
Scott Lang: No, I'm the Ant-Man!... I know, it wasn't my idea.
Scott Lang: Sorry I'm late, I was saving the world. You know how it is.
Scott Lang: [Demonstrating his Ant-Man suit to his crew for the first time] Now, look. This is gonna get weird, all right? It's pretty freaky, but it's safe. There's no reason to be scared.
Luis: Oh, no no. Daddy don't get scared.
Scott Lang: Really?
Luis: Yeah.
Scott Lang: Good.
[Closes his helmet and pushes the button that shrinks him]
Kurt: [Gasps, jumps out of chair] This is the work of gypsies!
Dave: That's witchcraft!
Luis: [Keeping his cool] That's amazing. That's like some David Copperfield shit!
Dave: That's wizardry!
Kurt: Sorcery!
Luis: How'd you do that, bro?
Scott Lang: Don't freak out, look at your shoulder.
Luis: [Looks at his shoulder, starts screaming, and runs out of the room] Get if off! Get it off!
Scott Lang: I thought Daddy didn't get scared!
Cassie Lang: Daddy, is that you?
Scott Lang: Hi, peanut!
Cassie Lang: Are you trying to find my daddy?
Paxton: Uh, yeah I am, sweetheart. I just want your daddy to be safe.
Cassie Lang: Hope you don't catch him.
Hank Pym: You're full of shit Scott.
[from trailer]
Hank Pym: [to Scott] It's not about saving our world. It's about saving THEIRS.
[Scott looks at his daughter]
Scott Lang: Pick on someone your own size!
Hank Pym: It's a trial by fire, Scott... or in this case, water.
[the bathtub fills with water, and Scott jumps out]
Hank Pym: Guess you're tougher than you thought.
Gale: [seeing the blown up ant] That is one messed up looking dog.
Sam Wilson: I know a guy.
Darren Cross: [at a function] Imagine a soldier the size of an insect, the ultimate secret weapon...
Hank Pym: [to Hope] You give godlike powers to everyone, it's gonna be chaos!
Hope Van Dyne: So how do we stop him?
Hank Pym: I know a guy...
Hope Van Dyne: [to Scott] The suit has power, and you have to learn how to control it... and these are your greatest allies.
[Scott meets an ant]
[Scott shrinks himself]
Hank Pym: The world sure seems different from down here, doesn't it, Scott?
Scott Lang: Who said that?
[from trailer]
Hank Pym: Scott, I've been watching you for a while, now. You're different. Now, don't let anyone tell you that you have nothing to offer.
Dale: Baskin-Robbins always find out.
Scott Lang: I love you, Cassie.
[sabotages the Yellowjacket regulator in a kamikaze move]
Scott Lang: [after going through the key hole successfully] Nailed it!
Darren Cross: You tried to hide your suit from me, now, it's gonna blow up in your face, and destroy everyone you care about.
Cassie Lang: Are you a monster?
Yellowjacket: Do I look like a monster?
Cassie Lang: [freaks out] I want my daddy!
Yellowjacket: I want him too.
Cassie Lang: Mommy, is daddy a bad man? I heard some grown-ups talking. They said he was bad.
Maggie Lang: No, he's not bad. Daddy just gets confused sometimes, you know?
[post-credits scene]
[Sam Wilson and Steve Rogers are in a garage with the Winter Soldier whose metal arm is trapped in a vice]
Sam Wilson: This would've been a lot easier a week ago.
Steve Rogers: If we call Tony...
Sam Wilson: He won't believe us.
Steve Rogers: Even if he did...
Sam Wilson: Who knows if the accords will let him help?
Steve Rogers: We're on our own.
Sam Wilson: Maybe not. I know a guy.
Scott Lang: [to Hank and Hope] Don't worry, he can't see me.
Sam Wilson: I can see you!
Scott Lang: He can see me...
[scales up, and unlatches helmet]
Scott Lang: Hi, I'm Scott.
Hope Van Dyne: [shocked] Did he just say "Hi, I'm Scott."?
Hank Pym: Scott?
Scott Lang: Yeah?
Hank Pym: You're full of shit.
Scott Lang: Oh yeah.
Scott Lang: I think our first move should be calling the Avengers.
Hank Pym: I've spent half my life trying to keep this technology out of the hands of Stark.
Hank Pym: I'm sure as hell not going to hand deliver to one now.
Hank Pym: This doesn't cue technology like the Iron Man suit.
Hank Pym: This could change the techs of reality.
Hank Pym: Besides, their probably too busy dropping cities out of the sky.
Scott Lang: We're trapped, now what do we do?
Hank Pym: Do you think that's a toy tank on my key-ring?
Scott Lang: [raises hand] Excuse me, Dr. Pym?
Hank Pym: You don't have to raise your hand Scott.
Scott Lang: [lowers hand] Okay. I just have one question... Who are you, who is she, what the hell is going on here, and can I go back to jail now?
Hank Pym: I took on a young protégé called Darren Cross.
Scott Lang: Darren Cross. He's a big deal.
Hank Pym: But before he was a big deal he was my assistant. I thought I saw something in him, a son I never had perhaps. He was brilliant, but as we became close he began to suspect that I wasn't telling him everything. He heard rumors about what was called the Pym Particles, and he became obsessed with recreating my formula. But I wouldn't help him so he conspired against me and he voted me out of my own company.
Scott Lang: How could he do that?
Hank Pym: The board's chairman is my daughter, Hope. She was the deciding vote.
Dave: Baskin-Robbins don't play!
[post-credits scene]
Sam Wilson: [looking at Bucky] This would've been a lot easier a week ago.
Steve Rogers: If we call Tony...
Sam Wilson: [interrupts] No, he won't believe us.
Steve Rogers: Even if he did...
Sam Wilson: [interrupts again] Who knows if the accords will let him help.
Steve Rogers: We're on our own.
Sam Wilson: Maybe not. I know a guy.
Hank Pym: You've come for more toys for the boys?
Howard Stark: I came for the suit.
