Former British child star Nicholas Hoult has scored back-to-back number ones at the box office in America after taking his new film Jack The Giant Slayer to the top.

Less than a month after his zombie comedy Warm Bodies hit number one, the About A Boy star is back there with his new film.

But the blockbuster, dubbed the first big-budget action film of the year, was anything but a killer at the weekend box office - the movie, which cost almost $190 million (£119 million), debuted at the top with a $28 million (£17.5 million) take.

Hit comedy Identity Thief has come in second on the new U.S. box office countdown, while college party comedy 21 & Over debuts at three and horror sequel The Last Exorcism Part Ii opens up at four.
