Audio problem: When Aaron attacks "Bishop II", he yells, "F***in' android.", but the words don't match the movement of his lips. (01:41:45)
Audio problem: Right before the people from the company enter the prison, Jude is being chased by the alien. He yells, "Help me.", but his mouth is wide open and the words don't match the movement of his lips. The same thing happens when he yells, "Please" shortly afterward. (01:31:10)
Continuity mistake: Any shot of the alien which isn't made using a guy in a suit has a green glow around the alien's body but any guy-in-a-suit shots do NOT have a green glow.
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.
Andrews: Exactly.
Trivia: Originally, the movie was going to be shot by cinematographer Jordan Cronenweth, but Cronenweth suffered Parkinson's Disease midway through filming and was let go by the line producer, being replaced by Alex Thomson. However, impressed by Cronenweth's work, David Fincher later worked with Cronenweth's son Jeff in nearly all of his future movies, resulting in two Academy Award nominations.
Answer: She means that the alien it moves on 4 legs, whereas the other aliens moved primarily on two legs. This alien came out of a dog in the theatrical version and from an ox in the Assembly cut version, which can only move on 4 legs. This hints to the fact that the alien inherits the characteristics of its host.
