MONSTER star Charlize Theron found the best way of coping with the stress of playing a sexually harassed character in her new film was to pester all the men on set.

In her new movie North Country, the Oscar winner plays a struggling single mother who has to endure endless insults and assault from her male colleagues.

Theron says, "On breaks between filming, I would get my own back by sexually harassing all the men on the set.

"It was quite a laugh and I think they quite enjoyed it. In fact my co-star Woody Harrelson came in one time on his day off and when I asked him why, he replied, 'I've come in for my sexual harassment!'"
