Continuity mistake: When Eli enters Daniel's office, as he goes to sit down his hand move from in his lap, to his side, then back again.
Factual error: There are a number of computers and gadgets shown which were not introduced in early 2002, i.e. HP LaserJet 1320 Printer at Asra's place, HP Color LaserJet shown at the consulate, Acer Notebook used in investigation, and the Nokia 1100 cellphone used by Captain.
Factual error: In the beginning of the film, a variety of different suitors are presented to Elizabeth. Amongst them are Eric XIV of Sweden, reportedly "still madly in love [with her]". Even though he was born the same year as Elizabeth; when this film takes place, in 1585, he had already been dead for 8 years.
Continuity mistake: The writing on Ghost's sword early in the film has the Turisas rune (representing TH in Thunder) near the hilt, but later not only is a different font used but now the Dagalas rune (representing the D in sword) is at the hilt.
Factual error: The movie depicts Wes Studi, who is playing the Paiute medicine man "Wovoka," as coming to the Sioux reservation and delivering his vision. Wovoka (aka Jack Wilson) was from Schurz, Nevada 1250 miles away from the Pine Ridge Reservation in South Dakota. He never travelled to South Dakota. What really happened was tribal parties (at great personal risk) travelled to Nevada to get the message and brought it back to the Sioux people. Of course, this message was "modified" somewhat to better fit Lakota culture.
Factual error: During the scene where Captian Less finds out his father was sent to Auschwitz by Eichmann, one of the maps on the wall displays a map of Europe. The map, however, is incorrect, and is a modern day map as opposed to how a map would have looked in 1961. At the time, the Czech Republic and Slovakia didn't exist as separate entities, Germany was not unified, Yugoslavia was yet to dissolve and Ukraine, Belarus, Estonia, Latvia, Lithuania and Moldova would not have appeared as separate states. (00:43:45 - 00:45:35)
Factual error: The movie is set in Philadelphia, but the bus at the beginning crashes at a crossroad in front of the fast food joint Admiral Submarine, a recognizable location in Brantford, Ontario, where the movie was shot. (00:05:00)
Factual error: In several scenes, the lead character drives a Toyota Land Cruiser with a grille bearing the Toyota emblem. This design was only introduced in the 1995 model. Since the film is set between late 1993 and April 1994, the correct grille should have had "TOYOTA" lettering across the front. (00:13:01 - 00:14:26)
Continuity mistake: In the scene where Henry is pouring the whiskey into the cups, the bottle is half empty when completed. Next scene Henry is nursing the bottle which is now almost full. (00:06:00)
