The "former lover loathes and stalks their ex's new partner" can be a tricky genre to pull off: a few twists and turns one way and you've a silly, straight-to-video cheesefest. Katherine Heigl and Rosario Dawson will be hoping to avoid that fate for Unforgettable, which has put its first trailer online.
Unforgettable finds producer Denise Di Novi slipping into the director's chair for the first time, and bringing to life the story of Tessa Connover, who is having a tough time of it. Not only has her marriage to David (Geoff Stults) ended, but now she has to contend with him moving on happily to Julia Banks (Dawson). Soon, he's engaged, and living with Julia in the house he once shared with Tessa, alongside their daughter Lilly (Isabella Rice).
Tessa's jealousy curdles into pathological issues, and soon... well, you can probably guess, and the trailer spells it out a little too clearly. The film itself was once going to be an Amma Asante project, but though she got to the casting stage, she's no longer involved. Unforgettable will stalk into UK cinemas on April 21.
