Best. Fact. Ever.
When Christopher Reeve first got the part of Superman, he was tall and fairly athletic but not all that muscular. So he took an intensive training programme to bulk up, which was run for him by David Prowse – weightlifting champion, Green Cross Code Man… and the occupant of the Darth Vader suit.
One of the great movie clichés is the training montage. Wouldn’t you just love to see one of Darth Vader training Superman?
