"Becoming Roy Bean was an all-consuming project. Walter worked late into the night "making the old fellow come alive." Weeks of preparation went into his performance. "I have literally become that man and will never for a single instant compromise with his character," Walter insisted. "He must always be himself and never his brother or his uncle. I find myself eventually thinking like him." Brennan had to see it in his own eyes as he watched himself on the screen. Had he made Judge Bean come alive? "I always say that an actor is no better than his last day's rushes," he said. You cannot fool the camera, Brennan liked to say. "The camera picks up what you think and not what you say or do. The reason I'm proof of that is because I've seen me give some lousy performances, and I said, 'I wonder what I was thinking when I did that."
