Obsessed Movie

Obsessed stars Beyonce Knowles (Sharon) and Idris Elba (Derek) as a couple whose marriage is threatened by a sexy new office temp (Ali Larter) who relentlessly pursues Derek.

The Metromix Obessed review said the film was "a subpar thriller that falls into the classic B-movie trap of too much mundane dialogue, too little pulse-quickening action. Knowles has genuine movie star charisma, Larter gives good psycho and Elba could turn up on a Japanese game show and still retain his dignity."Metromix: Obsessed Review (April 24)
