The 'former lover who loathes and stalks their ex's new partner' genre can be a tricky one pull off – a few missed guided twists and turns and you have a silly, straight to video cheesefest. Katherine Heigl (Knocked Up) and Rosario Dawson (Trance) will be hoping to avoid that fate for Unforgettable.
The film finds producer Denise Di Novi slipping into the director's chair for the first time, and bringing to life the story of Tessa Connover (Heigl), 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 is 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 (Belle) project, but though she got to the casting stage, she is no longer involved. Unforgettable will stalk into UK cinemas on April 21.
