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.
Factual error: Catus Decianus actually managed to escape from the massacre at Camulodunum and fled to Gaul.
Factual error: At the beginning of the movie, Robert E. Lee addresses Francis P. Blair as 'General' once. Blair however was never a general and in fact never held any military rank.
Factual error: The movie uses a "website" of http://members.aol.juktm.html. This wasn't the correct address in 1998 (it would have had a .com in it). The "website" shown was probably a local file on the computer shown in the movie and the producers didn't want to invest the extra time to make a phony address bar. (00:53:20)
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.
