Katherine Heigl

Katherine Heigl has signed on to star in and produce the big-screen drama Life As We Know It — but Grey's Anatomy fans needn't worry about this new gig impacting Heigl's recently confirmed return to the ABC series.

Heigl — who is currently filming the Lionsgate thriller Five Killers, opposite Ashton Kutcher — is due back on the Grey's set in late July, now that her option for Season 6 has been picked up. And while a rep for the actress was unable to comment on the anticipated production start for Life As We Know It, it is unlikely the film commitment will affect her Grey's work. On multiple occasions — and as recently as this spring — Heigl has simultaneously juggled film roles and her portrayal of Dr. Isobel Stevens.

Life As We Know It revolves around a woman and a man whose respective best friends die in a car accident. Following the tragedy, they are left to share in caring for the deceased's orphaned daughter. Everwood creator Greg Berlanti will direct.

Heigl will next be seen on the big screen opposite Gerard Butler in The Ugly Truth, opening July 24.
