I didn't see the film but I always loved Stubby Kaye. Someone once wrote an evaluation of Brando's career, saying that he spent as much time performing as a movie star (Napolean . . . and, obviously, Guys and Dolls) as he did as an actor (On the Waterfront).
That's what is sad about Hollywood. There are far too many gifted actors who break onto the screen only to become movie stars. Granted, we need entertainment and we need story telling as we no longer gather around turf fires in small villages, but, it would be nice if actors could remain actors and impress us with their gifts.
