Revealing mistake: When Diana and John first enter the mobile home, there's a shot of a TV with a dented screen. It's very obviously an old CRT, but cathode ray tubes can't be dented - they're made of glass, and would not only crack and break, but would implode, since they contain a high vacuum inside. This is obviously a prop TV that has been "distressed" simply to make it look old. (01:09:01)

Revealing mistake: In the scene where Dave (Alan Tudyk) is brushing off Sid (Tony Hale) at the reunion, the camera from slightly behind captures jaw movements that don't match his speaking, and he continues speaking when there is no jaw movement at all. (01:47:00)

Revealing mistake: Near the beginning, when the car is lowered into the underground complex, the car is sitting on a section of the street pavement above. When shown underground, it's sitting on a rug or carpet that appears as if it were supposed to represent a dirt surface. There are even visible tire tracks. (00:07:20)
