The Remains of the Day (1993)

Factual error: In the scene towards the end of the film where Stevens (Anthony Hopkins) is about to walk into the Hotel to meet Mrs Benn (Emma Thompson) for the last time a modern Nat West Bank sign is clearly visible for about three frames in the top right of the screen. The Nat West Bank did not exist in 1956, where this scene is supposed to take place. At that time it was still the National Provincial Bank and the Westminster Bank. They merged some years later.

Stevens: You know what I am doing, Miss Kenton? I am placing my thoughts elsewhere while you chatter away.
