Revealing mistake: How on Earth can Selby get those skin tight T-shirts over that huge cast on her arm? They cannot possibly stretch any more than they already are - look at the scene where she and Eileen are checking the mail. There is no way that sleeve would fit over the cast without ripping! It is well beyond the capacity of that tight T-shirt to stretch to that extent! Obviously Christina Ricci had the cast fitted after she was in costume.
Visible crew/equipment: In the closeup of Evie when she is holding a spoon under her eyes, you can see the boom mic reflected in each spoon. (01:04:15)
Factual error: Tony Gregory, the politician that Veronica meets, is seen wearing a suit and tie. Tony Gregory the TD, made a point of never wearing a tie.
Audio problem: During the wild boar hunt, they are interrupted by Aleander who says, "Prince Frederick of Saxony. He refuses to surrender Luther to you, Your Holiness," but nothing matches his lip movements. He utters a couple of syllables, at most, out of sync with the two full sentences heard in the movie. (English DVD version). (01:03:15)
Continuity mistake: When Robert Crumb is looking at Harvey Pekar's drawings for comic-book ideas while the two eat in a restaurant, the level of the drink in Harvey's glass switches between full and two-thirds full several times.
Continuity mistake: When Pancho and Frank are bathing in the lake, you see an Italian Horn on Frank's necklace. The camera angle changes and it is now a medallion.
Factual error: When Griet is introduced to the camera obscura, far too much light is projected onto Vermeer's and Griet's faces. Camera obscuras don't make their own light; rather the image produced on the viewing screen is always dull.
Factual error: The final episode of "The Lucy-Desi Comedy Hour" when Lucy meets Ernie Kovacs, marks the finality for Lucy and Ricky Ricardo, and Fred and Ethel Mertz. By this time the shows weren't filmed before a live audience the way it's depicted in the movie. The producers of the show abandoned the live audience earlier than the final shows.
Factual error: When both Erica and Courtney are racing, you can see mountains in the background, although there are no mountains in Houston, their hometown.
Factual error: The movie takes place in Des Plaines, Illinois, with a couple of scenes from downtown Chicago. However, throughout the movie you can see both palm trees and mountains in the background, none of which actually exist in Illinois. The producers also point this out on the DVD commentary.
Visible crew/equipment: In the second episode as Geli takes out her bike, with a Hitler painting. You can than see a modern yellow jacket worn by the director an film crew standing in shot. All on the left of the car, before the camera pans into Geli for a close up. (00:13:50)
Revealing mistake: Why does the railroad station look so old? It should be almost new at the time of the film.
Continuity mistake: When Daniel Craig stays out late and, finally, comes home to his wife, he takes his tie off, but doesn't undo the top button of his shirt, but that button, suddenly, is undone.
