Continuity mistake: When Lucy comes home at the beginning of the movie she quickly buttons the top of her dress. While eating dinner, it is open and then buttoned again between shots.
Visible crew/equipment: When Fred and Bertha are walking together near the end, when Fred says, "I don't really think there's a future there," and Bertha replies with, "No?" the film crew is reflected in Bertha's sunglasses. (01:18:46)
Continuity mistake: At the end of the movie, the bloody handprint on the car changes entirely the second time it is shown. (02:02:45)
