Re: Bit roles before they were "famous"
Robert Duvall's first appearance was as Boo Radley in "To Kill a Mockingbird." He appears only at the end, but his off-screen character is referred to throughout the film (after all, Boo "is" the mockingbird the title analogizes to).
I also remember Duvall as an Evil Villain out to control the West on an episode of The Wild Wild West
('The Night of the Falcon', iinm, about 1967.)
