Asked (reported variously to be by everyone from unnamed English writer to by actor George Peppard) whether he followed the Stanislavski method of acting, Mitchum responded, "I follow the Smirnoff method."
When, on August 31, 1948, police busting Mitchum for intent to possess marijuana asked him his occupation, the pessimistic answer came: "Former actor."
Mitchum replaced Edward Woodward (not as Woodward's character, Robert McCall, the Equalizer, though) in two episodes of The Equalizer after the star of the CBS series was felled by a heart attack. Woodward recovered and resumed the title role.
