Director: Noah Baumbach. Cast: Ben Stiller, Greta Gerwig, Jennifer Jason Leigh, Rhys Ifans. 107 min. Rated R. Drama.
Rule: Comedians' best films are their serious dramas (Williams in Awakenings, Carrey in Man on the Moon, Sandler in Spanglish). Greenberg shows Stiller's serious side, and the result is remarkable. As a morose loner who hates everybody and everything (even himself), he initially portrays an offensive loser, but then you realize he's really not that far off, as some of what he says touches a nerve - reminiscent of the "insane" brother (Michael Shannon) in Revolutionary Road, the only sane person in the story. Hope to see Steve Carrell, Tina Fey and Ricky Gervais in serious drama one day too.
