Will Smith and his daughter Willow Smith are set for a big screen battle in July when their new films are released on the same day. Seven-year-old Willow Smith's film Kit Kittredge: An American Girl is set to hit U.S. theatres on 2 July - the day her father's new superhero movie Hancock opens. And the actor has already let his daughter know he plans to win the box office crown. Willow explains, "He said, 'Sorry baby, but I got to stomp on you.'" "He thinks he is going to be beat me, but I think not. I think I am going to beat him."
