The Batman Begins sequel The Dark Knight has set another record at the U.S. box office by becoming the first film to pass the $300 million in just 10 days.

The film became the first movie to hit the $200 million mark in five days after breaking all opening-weekend box office records last week.

Thanks to a staggering $75.6 million ($37.8 million) secondweekend take, the Batman film has racked up over $314 million since its release in America 10 days ago.

It took previous record holder Pirates of the Caribbean: Dead Man's Chest 16 days to pass the $300 million mark in 2006.

Meanwhile, Will Ferrell's new comedy Step Brothers opened big in second place with a $30 million opening weekend take and Abba movie musical Mamma Mia! slipped to third with $17.9 million.

The new X-Files film, The X-Files: I Want To Believe, was a disappointment in its first weekend on release - it took in just $10.2 million.
