Other mistake: When in the tub in Arkansas, Wyatt is bare chested. In bed with Josie he's suddenly sprouted a lush garden of chest hair.
Continuity mistake: Stuart Sutcliffe talks in a Liverpool accent throughout the film. However, unlike the other Beatles, Sutcliffe didn't have a Liverpool accent. He was born in Scotland and raised in Lancaster. He didn't come to Liverpool until he was 16.
Continuity mistake: At the wrap party for "Bride of the Atom," when Dolores starts screaming at Ed "These movies are TERRIBLE!" her hair is curled in ringlets that hang down to the tops of her shoulders. She then stalks out of the warehouse, and Ed follows her. When he catches up to her in the parking lot, and she tells him she is leaving him, you can clearly see that her hair is suddenly much shorter and curlier.
Factual error: In the opening shot of the film, a big oak door opens - carved in it is the date 1862 - 42 years after George III died.
Factual error: What on earth is the conductor at the premiere of the 9th doing with a baton? This was not used until around 1849, and the premiere of the 9th is in 1824.
Continuity mistake: In the scene where Lane, Tuff and Cody are talking about Leffow right before Lane rides there is no leather strip around Lane's neck to tie his glove on with. In the next shot he has the leather strip around his neck. (00:28:35)
Factual error: In one scene Cobb and the sportswriter doing his biography are driving across the country to get to the baseball Hall of Fame. They are stopped next to some railroad tracks fixing a flat tire, and a train goes by that has Burlington Northern markings (BN). Burlington Northern didn't come into existance until ten years or so after Mr. Cobb died.
