Geoff Stults 'Didn't Like' Being Around Katherine Heigl While Shooting 'Unforgettable'

Geoff Stults is dishing on how method Katherine Heigl was on set while filming their latest film Unforgettable that it made him “uncomfortable.”

In the flick, which hits theaters on April 21, Katherine plays a woman who sets out to make life hell for her ex-husband’s (Stults) new wife (Rosario Dawson).

“That character was something she obviously worked really hard on, she had to wear it,” Geoff, 39, told ABC. “It’s a lot of preparation, her posture, the way she carried herself. I didn’t like being around her until the end of the day when she came out of it. Really, its uncomfortable, it’s scary. She does a wonderful job.”
