Who played Beyoncé’s love interest in the 2009 film Obsessed?

Idris Elba played Beyoncé’s husband and love interest in the 2009 film Obsessed.

Directed by Steve Shill, Obsessed is a psychological thriller released in the United States on April 24, 2009. Beyoncé plays Sharon Charles, a woman whose marriage is threatened when a temporary co-worker, Lisa Sheridan, becomes fixated on Sharon's husband. Idris Elba plays Derek Charles, the husband at the center of the conflict.

The film also stars Ali Larter as Lisa and Jerry O'Connell as Ben. Obsessed was one of Beyoncé's prominent acting roles during the period when she was balancing film work with her music career. The movie opened at number one at the North American box office and earned more than its production budget.

Viewers sometimes confuse this cast with Beyoncé's role in Dreamgirls, where she played Deena Jones, or with Cadillac Records, where she portrayed singer Etta James. Obsessed is a modern domestic thriller, not a musical biography.
