The 25-year-old says doing a comic act in the film makes her feel relieved, reported Aceshowbiz.
"When I first started acting I was always playing the mean girl, then I was playing these cool, robotic women. I was growing tired of playing those kinds of characters and reinforcing this stereotypes of me and having to play up to that when I was doing interviews.
"Now I feel I can be myself again. It's given me the chance to get away from that sexy, icy image that I've been stuck with. I think the public can relate to me more easily in these kinds of movies," Fox said.
Though she only tackles a minor part in the movie, Fox said that she had a wonderful time working with Sacha Baron Cohen.
"I had a wonderful time. Sacha is very smart and funny. We had a great time working together. I think the audiences are going to love the film," she added.
