Character mistake: Paul Walker is told of a 240SX with an illegal mod. You then see it is an S15. There was never an S15 240SX. It is a Japanese spec 200SX, chassis code S15.
Character mistake: When discussing the new Pope's name (Luke) at the end of the film, Langdon says: "There have been many Marks and Johns, but never a Luke." In fact, though there have been 23 Pope Johns, there has only been one Pope Mark - reigning for 9 months in 336.
Character mistake: Candy's full name is Candace Washington, which is referred to in the movie, yet when she is released early from prison, the correction officer calls her Candace Collins.
Character mistake: The opening shot of the movie pans across a fence supposed to enclose the hunting reservoir of the royal family of the fictitious kingdom of Vespania. Judging by the sign on the fence, the official language of the country must be EngRish; the sign says "Land Demesne We knownothing [sic] about FIRE!", citing also as source for these cryptic messages the "internal secuLity act of 1950."
