Katherine Heigl's next movie ‘Unforgettable’ is definitely not a rom-com

Break ups are hard, but in the new movie "Unforgettable", Katherine Heigl's character Tessa Connover is taking it particularly hard. 

The first trailer for the film shows Tessa becoming more than a little unhinged as her ex-husband David (Geoff Stults) finds new love in Julia Banks (Rosario Dawson). 

Tessa becomes obsessed with taking her old life back, putting Julia in danger as the past resurfaces. 

"Unforgettable" is the directorial debut of Denise Di Novi, whose credits as a producer includes "Crazy, Stupid, Love" and the classic '80s film "Heathers."

"Unforgettable" opens in Philippine theaters in 2017. — AT, GMA News
