TOD:
I used to think Boyd Gaines was my favorite character actor, from when he was giving terrific performances in hit stuff like "Porky's" - but I was reminded that while he may be a character actor to film people, but he was already on his way to being a star in theater.
(He was already on :One Dat at a Time," I think.)
Is Nathan Lane like that, too, for Broadway huge star vs, screen character actor? Maybe Bernadette Peters? Always wonderful on film, where they seemed to be character actors, but you can sell investors based on their involvement on Broadway, and their names make productions happen.
