Box office: 'Jack the Giant Slayer' tops slow Friday with disappointing debut

Bryan Singer's "Jack the Giant Slayer" -- starring Nicholas Hoult and Ewan McGregor -- may not live happily ever after at the box office. The pricey pic earned $7.7 million on Friday night, and will likely pick up around $25 million for the weekend. It was enough for the film to debut at No. 1, topping fellow newcomers "21 & Over" and 'The Last Exorcism Part II."
