California Doubling: Filmed almost entirely in Ireland. Would that be California Dublin?
Completely Different Title: The movie was titled The First Great Train Robbery in the U.K., to distance it from the two million pounds sterling robbery from a mail train in 1963, which was known in the British press as "The Great Train Robbery".
In Memoriam: Dedicated to the memory of cinematographer Geoffrey Unsworth: "His friends miss him."
Sean Connery performed most of his own stunts in the film, including the extended sequence on top of the moving train. Filming the scenes proved quite difficult for him as cinders from the locomotive kept getting in his eyes. This was made even worse by the train going much faster than expected.
In a 2011 BBC radio interview, Wayne Sleep (Clean Willy) told how he was asked by Michael Crichton to climb a sixty foot wall. Sleep's response was "I'm an actor, not a stuntman." When Crichton explained that they had not been able to find a stuntman small enough (Sleep is 5'2"), Sleep made the climb anyway.
Nick Nolte was keen to appear in this movie, but producer Dino De Laurentiis would only agree if Nolte also appeared in Orca, and Nolte balked at that idea.
