Sarah Michelle Gellar has signed to star in the Hitchcockian thriller ADDICTED. Yari Film Group will finance the film, to be produced by Yari, Vertigo's Doug Davison and Roy Lee and Spitfire Pictures' Guy East and Nigel Sinclair, says The Hollywood Reporter.

Swedish filmmakers Joel Bergvall and Simon Sandquist will direct the film, set for an October production start. The duo is signed to direct the Warner Bros. Pictures big-screen adaptation of DC Comics' "Books of Magic."

ADDICTED centers on a woman whose husband and brother-in-law both end up in a coma after an accident. When the brother awakes, claiming to be her husband, she must try to understand the reality, suspecting something more sinister is at work.

The screenplay was adapted by Michael Petroni from the 2002 South Korean film "Jungdok."
