Visible crew/equipment: Just as Eddie rides his motorcycle down from the lab's upper level, in the shot from behind him, set equipment and a few crew members are seen gathered at the top right of the screen, just before the shot cuts away. (00:44:40)
Continuity mistake: During "Eyesight to the Blind," The Preacher's guitar changes from a red Les Paul to a black Stratocaster. It's not blatantly obvious, but easy enough to spot without slow-mo. (00:26:33 - 00:30:02)
Audio problem: In the "How Lucky Can You Get?" musical number, when Fanny is turning on the stage lights she is not singing, although Streisand's singing voice is heard on the soundtrack.
Factual error: When Charlie is talking to his old boss in the 60s, a 1970's Triumph Dolomite is parked behind them.
