Factual error: In the opening robbery Chuck is sporting a Smith and Wesson model 686. The scene was depicted in 1972. The 686 didn't come out until 1980.
Continuity mistake: When the vault is about to be opened, the drilling equipment is attached to the door, but the view from the camera watching the door being opened shows no equipment.
Factual error: When the bank robbers pull the money out of the vault, they claim all the cash is from 1982. Yet most of the bills have large faces, which was introduced into rotation in 1996.
