Roy Alon (1942 - 2006)
- The Long Good Friday (1980) [Captain Death]: Shot with a shotgun during a betrayal during a meeting with Bob Hoskins. His body then falls out a window and is run over by a car.
- Never Say Never Again (1983) [Prison Guard]: Drowns after being thrown out a window by Sean Connery.
As a professional stunt performer, (in fact the most prolific once recorded by Guinness), he has undoubtably 'died' in place of other actors, though I don't know any examples.
