6. Gladiator - "The Spaniard"
Any fans of Russell Crowe and his famous role of Maximus Decimus Meridius? Well, his character in the movie is also called 'The Spaniard,' which is, in fact, an old French word that was invented in the 1300s.
It was a silly mistake from the writers as the Gladiator movie was set in 180 AD, a thousand years earlier!
