In the new psychological thriller UNFORGETTABLE Katherine Heigl plays Tessa Connover, a possessive woman that becomes increasingly consumed by jealousy and, ultimately, madness.

I recently had the pleasure of seating down with the incredibly talented performer to talk about her role, shooting those intense fights, and more.

The film, directed by Denise Di Novi, also stars Katherine Heigl, Cheryl Ladd, Geoff Stults, and Whitney Cummings.

UNFORGETTABLE will be released in theaters on April 21.

Tessa Connover (Heigl) 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, Lily. Trying to settle into her new life, 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.
