Factual error: Prime Minister Peter Stolypin is shown at the Romanov Tercentery, which marked 300 years of Romanov rule. Stolypin died in 1911, yet the Tercentenary was held in 1913. Also, Alexei's Spala incident happened in 1912, and was also shown after the Tercentenary.
Factual error: The year is 1969 when they steal the first aircraft (single engine Cessna), and there is a 757 taking off in the background. The 757 first flew on 02-19-82. (00:22:05)
Continuity mistake: When Ed is taking his tie off after the meeting with the PG&E clerk, he loosens it, then they cut to Erin, then back to Ed, and his tie is back to tight around his neck, and he's taking something out of his breast pocket. Then they cut back, and his tie is off. (00:52:42)
Factual error: When they show the Nelson Eddy song 'I Love You', the set/movie shown is Rose-Marie. But that number is from Rosalie not Rose-Marie. Two totally different movies - one set in West Point not with the Canadian Mounties. There are no Cole Porter songs in Rose-Marie, likewise there are no Mounties in Rosalie. Rose-Marie's music was by Harbach / Hammerstein II / Friml / Stothart. (01:09:25)
Factual error: When Eakins returns to the house after he swears an oath to the union. You can see a thermostat on the wall behind him. (01:40:00)
Factual error: The Nina, Pinta, and Santa Maria are shown starting back for Spain at the end of the first voyage. In fact, the Santa Maria had wrecked by this time; the return voyage would be made only by the Nina and the Pinta.
Factual error: Jan Christiaan Smuts is referred to as the Prime Minister of the Union of South Africa in this film when Gandhi is there. Smuts didn't gain the office until 1919, after the death of Prime Minister Louis Botha. Gandhi left South Africa in 1914 and never returned.
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: Whale commits suicide by drowning himself in the pool. When Clayton pulls him out the color of Whale's suit changes from black to brownish, and vice versa when Clayton throws him back in. Varying degrees of wetness should not be the reason as he should be drenched too while he is lying at the poolside. (01:33:40)
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.

Deliberate mistake: In the scene where Marie is trying on shoes, a pair of powder blue high top Converse sneakers can be seen next to her feet. It must have been done intentionally, but since there is no trace of modern apparel anywhere else in the film (the closest would be the mere mention of hot pink dress fabric but, as it's not shown, we don't know what exactly Marie calls "hot pink") these shoes (and the fabric) can't be considered part of a thematic element or artistic license.
