Take a first look at the one sheet poster for Katherine Heigl’s upcoming movie Unforgettable. The Warner Bros. dramatic thriller, which also stars Rosario Dawson, Geoff Stults, Isabella Rice and Cheryl Ladd, hits the big screen from April 21.

In the film, Katherine stars as Tessa Connover, who is barely coping with the end of her marriage when her ex-husband, David (Stults), becomes happily engaged to Julia Banks (Dawson)‚ not only bringing Julia into the home they once shared but also into the life of their daughter, Lilly (Isabella Rice). Trying to settle into her new role as a wife and a stepmother, Julia believes she has finally met the man of her dreams, the man who can help her put her own troubled past behind her. But Tessa’s jealousy soon takes a pathological turn until she will stop at nothing to turn Julia’s dream into her ultimate nightmare.

Warner Bros. have also released an animated version of the movie poster, which hints at dark events to come:

The R rated picture is the first film in the director’s chair for veteran producer Denise Di Novi and marks a reunion with Katherine Heigl. The duo previously collaborated on Life As We Know It which grossed over $100 million worldwide.
