I came across this story in Granta today (courtesy of the Awl, home of many worthy things), and really enjoyed it. Give it a read?
Haha, from Wikipedia:
Mitchum is regarded by critics as one of the finest actors of the Golden Age of Hollywood. Roger Ebert called him 'the soul of film noir'. Mitchum himself, however, was self-effacing; in an interview with Barry Norman for the BBC about his contribution to cinema, Mitchum stopped Norman in mid flow and in his typical phlegmatic style said, "Look! I have two kinds of acting. One on a horse and one off a horse. That's it."
I watched the original Cape Fear recently. I picked it up because I thought Mitchum was so amazing as the villain in Night of the Hunter. I love a good villain.
