Factual error: In the shot of the infield at the Saratoga racetrack several Canada geese are shown landing. However, the calls inserted on the soundtrack are the quacks of mallard ducks not the honks of Canada geese.
Visible crew/equipment: In the scene near the beginning of the film, when the 2 brothers are fixing to leave to join the army. After the mother gives them the flag, the shot changes to the 2 brothers. You can see the boom mic and the camera in the reflection of their shiny brass buckles.
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)
Factual error: Catus Decianus actually managed to escape from the massacre at Camulodunum and fled to Gaul.
Continuity mistake: As Michael leaves after being fired and Chuck returns to the office, the clocks in the newsroom read drastically different times in each shot, even going backward through time at one point.
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)
Factual error: During the film, there are extracts of two songs - 'The Spy' and 'Maggie McGill' - from the Doors' fifth album, Morrison Hotel. Great songs, however the film is set in 1968 and Morrison Hotel was not released until 1970.
