Revealing mistake: When they fix the door, in the last few frames we see while the door is still moving up, the gear stops spinning in the "rail".

1 revealing mistake
Directed by: Phil Tippett
Starring: Kelly Carlson, Richard Burgi, Billy Brown, Cy Carter
Continuity mistake: When the sergeant crushes the bug with her rifle's butt in the incinerator, we can read "The bug stops [...]" on the side of the stock and the butt is flag. In the next shot where she unfolds Dax, the text is gone and the butt has a clear bump at the bottom.
Pvt. Lei Sahara: There're too many of them, Dax.
Captain Dax: You've gotta tell 'em what you saw, Sahara. You gotta tell 'em about the new bug.
Pvt. Lei Sahara: You stay here, you'll die.
Captain Dax: Murderers don't go home.
