Often misquoted line, even in subtitles (spoiler):
After Brett gets snatched up in to the duct and the group is discussing it in the mess hall, Lambert asks a line which is kind of hard to understand, and Ripley even asks Lambert to repeat it, but when she does she asks something slightly different:
Lambert: Could it want Brett alive?
Ripley: What?
Lambert: Could Brett be alive?
Ripley: No... I-I don't think so.
