1. - Bud Cort, Harold and Maude, 1971. Other actors competing for Harold Chansen included unknowns Daniel Fortus, John Neilson, John Rubinstein, Todd Susman... and Elton John!
2. - Richard Dreyfuss, American Graffiti, 1973. “In the beginning of my career, I was 25 but I’d played a teenager in Making It. I found it oppressive, worrying about my hairline and wrinkles... Then, George Lucas was interested in me playing a teenager in some movie. I said: I don’t think it’s good for one’s career to be a teenager when you're 25... I’ll try and get adults parts from now on.” Four years later, he made Close Encounters of the Third Kind with Dreyfuss and is often mistaken for him or Charles Martin Smith “and Rick Moranis occasionally - but not often!”
3. - Tom Wilkinson, Dedication, 2007. Due to be Billy Crudup’s book illustrator (and eventual ghost) until promoted (?) to his book publisher. But Balaban and Mia Farrow churned into Wilkinson and Dianne Wiest.
