Too bad that there weren't more actors like Mercedes McCambridge, who'd go to work for Welles in a movie just because he was directing it...
From A QUALITY OF MERCY
The autobiography of Mercedes McCambridge:
Only a certain breed of actor should ever even try to work for Orson Welles. I'm glad I'm one of that breed. Orson was one of the highest peaks in my life.
One day in Hollywood, when I was minding whatever was my own business, of the moment, the phone rang, and it was Orson Welles. He was filming Touch of Evil, in the late fifties, and he wanted to know if I could come out to the set in time for lunch. Sure I could. Did I have a pair of black slacks and a black sweater? Sure I had. Did I have a black leather jacket? I said I wouldn't be caught dead in a black leather jacket. He said never mind, come anyhow. I went.
At four o'clock that afternoon I was back in my house minding again whatever was my own business. I had been in a movie in the time between Orson's phone call and the stroke of four.
That's what it is like to work for Orson Welles. A phone call or a cryptic telegram giving no information whatsoever serves as the summons, and if you are like me, you drop everything and go to wherever Orson is… no script, no talk of money, billing, nothing… go!
