Two weeks after the limited release of comedy Whatever Works, writer-director Woody Allen credits its star, Curb Your Enthusiasm creator and star Larry David for the believability of the film's central character.

"He's believable to me as an intellectual, as a guy who would know physics, who was cultivated, who'd be sardonic and opinionated and really very taken with himself," he tells San Jose Mercury News.  "And, as Zero was, insecure underneath.  Also, both of them could both play this kind of character, as Larry does on his television show, and there was still something about them that was vulnerable and likable."
