She may not get the same critical exposure like her acting colleagues, but she's certainly getting plum and starring roles. After co-producing and playing Etta James in 'Cadillac Records' for Sony BMG, Beyonce will switch gears and try another genre - thriller.

According to Variety, Beyonce Knowles, Ali Larter and Idris Elba will star in "Obsessed," a thriller that Screen Gems will put into production this summer.

Steve Shill will direct a script by David Loughery. Will ('Stomp The Yard, This Christmas') Packer produces, and Knowles will be exec producer along with her father, Mathew Knowles.

In "Obsessed," Elba will play an asset manager who has a knockout wife (Knowles) and thriving career until a temp office worker (Larter) begins stalking him.

Screen Gems topper Clint Culpepper is finalizing cast deals, working with Knowles' and Larter's reps to iron out scheduling kinks.

Knowles was last seen onscreen in "Dreamgirls," Larter in the Screen Gems films "Resident Evil: Extinction" and "Final Destination," and Elba last appeared in "American Gangster" and 'This Christmas.' He next stars in "Prom Night" for Screen Gems and will appear in BBC film 'The No.1 Ladies' Detective Agency' with Jill Scott.
