Dillon: You're all gonna die. The only question is how you check out. Do you want it on your feet? Or on your fuckin' knees... begging? I ain't much for begging! Nobody ever gave me nothing! So I say fuck that thing! Let's fight it.
Ripley: This is a maximum security prison, and you have no weapons of any kind?
Andrews: We have some carving knives in the abattoir, a few more in the mess hall. Some fire axes scattered about the place - nothing terribly formidable.
Ripley: That's all?
Andrews: We're on the honor system.
Ripley: Then we're fucked.
Andrews: I'm afraid we'll have to assume there's a very good chance this simple bastard has murdered them.
Dillon: Now you don't know that! He's never lied to me! He's crazy, he's a fool, but he's not a liar.
Andrews: We're 25 prisoners in this facility. All double-Y chromos. All thieves, rapists, murderers, child-molesters. All scum. Just because they have taken on religion doesn't make them any less dangerous. I try not to offend their convictions. I don't want to upset the order. I don't want ripples in the water. And I don't want a woman walking around, giving them ideas.
Ripley: I see. For my own personal safety.
Dillon: I wanna get this thing, and I need you to do it! And if it won't kill you, then maybe that helps us fight it.
Continuity mistake: Just after the doctor started the post mortem on that little girl, the front of his gown is covered with blood. Yet, a few seconds later, after the two other guys appeared, his gown looks better, with less blood. And during the whole post mortem scene, the blood spot actually changes its size a few times. (00:17:55 - 00:19:55)
Trivia: The plot of the movie is a combination of two spec scripts written for the film - one was by David Twohy (Riddick) who wrote a script set on a prison planet, and another by Vincent Ward, set on a monastery planet with the same characters and basic plot. Despite this, neither received credit for the screenplay (Although Ward received story credit).
