LOS ANGELES (AP):

It wasn't exactly a mighty victory, but Jack the Giant Slayer won the weekend at the box office.

The Warner Bros, 3-D action extravaganza, based on the Jack and the Beanstalk legend, made just $28 million to debut at No. 1, according to yesterday's studio estimates. It had a reported budget of about $200 million.

'Jack' comes from Bryan Singer, director of The Usual Suspects and the first two X-Men movies. It stars Nicholas Hoult, Ewan McGregor, Ian McShane, and Stanley Tucci.

Among other new releases, the college romp 21 & Over from Relativity Media made only $9 million this weekend to open in third place. And the horror sequel The Last Exorcism Part II from CBS Films debuted in fourth place with just over $8 million.
