Re: Who would play your hero(ine) in a movie?
I've never actually used actors or musicians as a basis for the look of a character.
My group did, however, use them outright. There was a Call of Cthulhu one-off where we all took the roles of prog-rock guitarists. I was Syd Barrett of Pink Floyd, someone else was Steve (The Pumpkin King) Howe of Yes, another guy was King Crimson's Robert Fripp, etc.
