The Deer Hunter
Robert De Niro says that this was his best performance ever and that it was also his most physically exhausting film.
The helicopter scene was filmed using Robert DeNiro and John Savage themselves. During this scene the runners caught on the ropes and could have seriously hurt the actors. DeNiro and Savage waved their arms and yelled at the crew inside the helicopter to warn them. The footage of them waving their arms was left in the film.
