Other mistake: When the family is leaving and the door is shut you see the floor lock (common in older homes) on the door engage. When Brad goes back in through the window you see him run down the stairs. He gets to the door and unlocks 2 locks on the upper part of the door but not the floor lock.
Critters (1986)
1 other mistake - chronological order
Directed by: Stephen Herek
Starring: Billy Zane, Dee Wallace, M. Emmet Walsh, Billy Green Bush, Scott Grimes
Continuity mistake: After Charlie shoots April in the ass with the slingshot, she immediately turns around to see who did it. Charlie is holding it as he says "Oops" and Brad takes it from him, all the while April is turned completely towards them. Couldn't she see it was Charlie and not Brad?
Ug: We're here for the Crites.
Trivia: One of the Krites is biting the head off an "E.T." doll. Dee Wallace coincidentally co-starred in both "Critters" and "E.T." as the mother of each film's respective young protagonist.
Question: Any particular reason why they chose not to have the Krites grow huge in the sequels?
Answer: Maybe it's because they didn't have the budget where they could afford to do such an idea.
