From Lloyd Robson's book OH DAD! A SEARCH FOR ROBERT MITCHUM:
"It's commonly believed that there was really only one reason why Mitchum never received an Oscar and that was his refusal to toe the line. He wasn't pliable, he wasn't controllable. If they put him on the stage in front of a worldwide audience, who knows what he might do or say? If you award the rebels, the individuals, what message does that send out to everyone else? If the troublemakers win awards, why should anyone else behave? Mitchum could never win; could never be seen to win. That's the nature of the game, and he knew it."
