Continuity mistake: When Quicksilver duct tapes the guard in the elevator, the tape changes when Quicksilver and Magneto come back. For example, when they get back, the tape on the chin is now tucked under tape strips and there are more spaces seen.

Factual error: The Mountain Dew logo seen in the stadium didn't come out until 1980, despite the film being set in 1973. The changes made in 1980 were subtle, but still distinct, especially the loss of the "wave" in the "D" and the smaller hole on the "a."

Trivia: Magneto's line "I don't know karate, but I know crazy" comes from James Brown's 1973 hit "The Payback." Although the actual lyrics are "I don't know karate, but I know ka-razor."
