The Great Train Robbery

Back when Michael Crichton was dabbling in directing, he made this movie, based on one of his novels. Sean Connery and Donald Sutherland conspire to pull off a jewel heist from a moving train — the first job of its kind — in 1855. True to the great caper genre, much of the time is spent plotting and preparing for the crime, including a wonderfully tense scene where the thieves sneak into a guarded office to make a copy of a key.
