The competition at the box office this weekend will not only occur between movies but also between movies and the Super Bowl. With that in mind two studios have decided to debut a chick flick and a horror flick, the only types of films that have shown a chance of luring moviegoers away from their TV sets. Universal is opening the Diane Keaton starrer Because I Said So, while Sony is debuting The Messengers (the latter without the benefit -- or distraction -- of a screening for critics). On the other hand, last week's top films, Epic Movie and Smokin' Aces, are expected to be thrown for a mighty big loss in their second week. In limited release, the Weinstein Co.'s controversial Factory Girl, about Andy Warhol clan member Edie Sedgwick, starring Sienna Miller in the title role, is scheduled to open in three theaters.
