Did she ever play Martha? She would have been amazing.
Roddy McDowall seems like an odd choice for Nick. (So did George Segal, frankly.)
I don't know much about the history of the film: was Redford ever approached (even for the stage version)? Or someone like Tab Hunter or Troy Donahue? Or am I misreading Nick? I always think that he's meant to be a golden-haired American beauty. But George Grizzard wasn't. Nor was David Harbour. And Albee had casting approval so maybe I'm wrong in assuming Nick is meant to be a young god?
