I've always been a big fan of Robert Mitchum,He was tough off screen as well as on,He was a talented amateur boxer.In 1953's Second Chance, He appeared with another boxer and tough guy Jack Palance,At the start of filming for the climatic cable car fight,Palance punched Mitchum full in the face,After recovering Mitchum returned the favour,Gutpunching Palance so hard He nearly vomited.Mitchum bent down to the retching Palance and said"Why don't We just pretend from now on ?"
