A scientist makes a last stand on Earth with the help of a ragtag team of soldiers against an invasion of alien phantoms.

Ryan: PLEASE tell me we're risking our lives for that little plant.
Jane Proudfoot: I wouldn't even call it a plant; I'd call it a weed.
Neil: I wouldn't even call it a weed.
[Neil and Ryan tamper with an elevator with passengers Grey and Aki]
Jane Proudfoot: What do you think you're doing?
Neil: We're just gonna stall them for a little while... Hey, don't look at me, it was HIS idea.
Jane Proudfoot: This was YOUR idea?
Ryan: We're just helping the Captain out a little. Have you seen the way he looks at her?
Neil: Yeah, Jane, where's your sense of romance?
Ryan: Two. Coming from the eighth wall.
General Hein: Report any aberrant behavior in Dr. Ross to the Major immediately.
Grey: "Aberrant behavior," sir?
General Hein: The woman carries an alien infection. It may be clouding her judgment. They may be manipulating her for their very own purposes.
Grey: Is the General suggesting Dr. Ross is a spy?
General Hein: The General is wondering why he's explaining himself to a Captain.
Alarm voice: Proceed to the nearest evacuation facility, Proceed to the nearest evacuation facility.
Neil: I think we should proceed to the nearest evacuation facility.
General Hein: Where is the PROOF?
Doctor Aki Ross: Here.
Neil: Jane, let me ask you something, do you think we're gonna get out of here alive? I mean I wonder if anyone else has gotten out. You think anyone's made it this far? huh?
Jane Proudfoot: Uhh...
Neil: You really think this 8. spirit stuff is really going to work against the phantoms? i mean, what if it's all a bunch of Mumbo Jumbo?
[gets a little electric shock]
Neil: Ahh... jeez Jane. do you mind if we stop talking? I'm trying to concentrate here.
Neil: Looks like you've gained some weight.
Jane Proudfoot: It's called upper body strength Neil. Get a girlfriend.
Neil: I'm working on it.
Neil: Speak to me, Sarge.
Ryan: Ouch.
Capt. Gray Edwards: The city may be lost, but we're not.
Aki: With the hope of new life has Gaia changed the phantom within.
[Grey's last words to Aki Ross]
Grey: I love you.
Neil: The controls are located here.
[He tries to open them, but can't]
Neil: Locked, naturally.
Aki: This mission was well worth the lives of you and your men.
Jane Proudfoot: "Men"?
Ryan: She thinks you're a man.
Jane Proudfoot: I think she's an idiot.
Neil: I know you're not a man.
Jane Proudfoot: I think YOU'RE an idiot too.
Aki: I just... I don't know how much time I have left.
Capt. Gray Edwards: Who does?
Neil: How could they survive a trip across space on a chunk of rock?
Aki: They didn't.
Neil: Oh... this is all beginning to make a creepy sort of sense.
Aki: What's happening?
Capt. Gray Edwards: Dr. Cid is implanting the Seventh Spirit directly into your body.
Aki: Then you must be my spiritual support. Gray, how sweet.
Doctor Sid: Oh, and stay away from your friend the Captain. You save his life, he saves yours, one thing leads to another... I was young once too.
Doctor Aki Ross: Doctor, there's a war going on. Nobody's young anymore.
Doctor Sid: Remember what happened to Galileo? They threw him in jail because he said the earth was not the center of the universe. That could happen to us.
[before driving through the windows to the landing bay]
Doctor Sid: So I gather this will be somewhat of a rough ride.
Neil: Doc, you got a talent for understatement.
[after the vehicle crashes dislocating two tires and losing one]
Doctor Sid: Interesting.
Grey: You've been trying to tell me that death isn't the end. Don't back out on me now that I believe.
Capt. Gray Edwards: I want you two back on the ship.
Neil: We're doing fine, Captain.
[Turns to see Jane fending off a horde of phantoms]
Neil: Jane is negotiating with extreme prejudice.
General Hein: I'll blast you all to hell.
[Jane fires a flare, and it reveals dozens of phantoms coming out of the ground]
Capt. Gray Edwards: What's going on down there?
Jane Proudfoot: Nothing we can't handle.
[Aki and Gray are standing in a giant crater, above which is a huge phantom]
Capt. Gray Edwards: This is not a good place to be.
[Looks down and sees swirling blue energy beneath them]
Capt. Gray Edwards: That's not what I think it is, is it?
Aki: Yes-it's Gaia.
Capt. Gray Edwards: This is definitely not a good place to be.
[after being told to deactivate the laser bars and they deactivate automatically]
Grey: Whoa. Neil, I'm impressed.
Neil: That makes two of us.
Jane Proudfoot: Fire in the hole.
Aki: We can't just leave everyone.
Capt. Gray Edwards: Everyone is dead.
General Hein: Oh my God. HOLD YOUR FIRE.
Aki: Only seven years old... and yet ready to die.
General Hein: [after letting the phantoms into New York City] What have I done?
Aki: All life is born of Gaia and each life has a spirit. Each new spirit is housed in a physical body. Doctor?
Doctor Sid: Go on.
Aki: Through their experiences on Earth, each spirit matures and grows. When the physical body dies, the mature spirit, enriched by its life on Earth, returns to Gaia, bringing with it the experiences, enabling Gaia to live and grow.
