Actress Elisha Cuthbert has revealed that he was so scared when she watched her new movie 'Captivity' that she threw up.

Elisha, who plays a model held captive by a stalker in the film, says that she found viewing the film �terrifying.�

She tells Radio 1, �When we finished filming and I watched it back I was physically sick. I got so into the part I started to believe that what was happening to me in the film was real.�

After the endless scrapes she got into in �24� you�d think that watching herself be buried alive by a psychopath would be a doddle.

Elisha also admits that she finds co-star Kiefer Sutherland attractive thanks to his �bad boy vibe.�
