Continuity mistake: Elaine and the policeman are talking at her place. He proposes to go to the bedroom and she says "I don't think so." He then asks why not, and puts his hand in front of his forehead. The hand position changes at the cut. (00:59:50)
Continuity mistake: Louise's husband is in the car with his nurse. She rubs his earlobe with her fingers; when he asks her about the wet towel and adds "I think I'd like that." her thumb is in front of the ear, but when she replies "I know you would" it's behind it. (01:03:40)
Other mistake: It's a funny line, sure, but when Jane is with her fiancé, he tells her that her mother and her lesbian partner "adopted a black baby" and "last week, she hocked her wedding ring to buy a crib." That's a little fast, considering the relationship happened just a little before the heist planning, a week. (01:04:20)
Continuity mistake: During the heist, the lights go out, but just the stage ones. Elaine asks for a flashlight; a guy with a short-sleeved light green shirt is sitting in the audience, or standing in the reverse shot. (01:27:20)
Continuity mistake: In the semi-POV of the security cart that takes a hard turn through the crowd, the off-balance guard is clinging to his colleague's shoulder, but he was nowhere near to reach him in the other shots. (01:30:30)
Other mistake: Elaine is counting her share of the loot in $20 increments; however the pile of money is not made of $20 bills. You can spot about 1 in the visible area, the rest are 1 or 5 dollar bills. Louise is shown stacking away all $100 and $20 bills. (01:38:30)
Factual error: It is established early in the movie (Natalie's call) that the money ball event celebration is part of the -first - anniversary of the Valley River Center, the shopping mall where most of the movie is set, with the town of Eugene, Oregon, mentioned explicitly. However, the center opened in 1969, and the movie is set in 1980. The original script was written in 1971, so that line needed an update and slipped by.
