Whatever Works (2009)

After a failed suicide attempt, brilliant New York misanthrope Boris Yellnikoff (Larry David) forsakes his posh upper-class existence for meager accommodations in Chinatown. He meets his exact opposite in Melody (Evan Rachel Wood), a pageant queen from the Deep South who's long on sweetness but short on smarts. Surprisingly, Boris and Melody marry, but the sparks really fly when Melody's born-again Christian mother (Patricia Clarkson) arrives and finds liberation instead of damnation.
