Actress Isla Fisher is set to follow in the footsteps of fiance Sacha Baron Cohen by launching a career in comedy. The Wedding Crashers star announced she has landed a GBP1 million ($2 million) contract to become a comedy star at the launch of her new movie Hot Rod. And the pregnant star has already begun dreaming up potential plots and comedic characters for the venture. She says, "I have a million characters in my head. I've always done characters ever since I was a kid. "There are not many great roles for female comedians. So I've been creating my own material."
