Robin Hood: Prince of Thieves (1991)

Factual error: Robin and Azeem land at the white cliffs and Robin says something like, 'Tonight we will dine with my father'. Those white cliffs are the Seven Sisters in East Sussex, about 200 miles from Nottingham. It would probably take about two weeks to walk it. They also reach Hadrian's Wall in the next scene, which is 200 miles further north than Nottingham.

Sheriff of Nottingham: Locksley! I'm gonna cut your heart out with a spoon.
Robin Hood: Then it begins.

Trivia: There was a series made in the UK (and very popular in many other countries) in the 80's called Robin of Sherwood. One of the characters was a Saracen called Nasir. He was not originally supposed to be one of the regulars, but the actor (Mark Ryan) got on so well with the rest of the cast, the decided not to kill Nasir, but keep him on as one of Robin's men. When Robin Hood Prince of Thieves was in development, a character called Nazeem was written because the writer thought that the Saracen was a traditional part of the legend (along with Little John, Will Scarlet and Marian). The name was changed to Azeem because they found out that the character was unique to Richard Carpenter's Robin of Sherwood. So, thanks to a random piece of casting in the UK in the 80's, we were given Morgan Freeman's Azeem.
