However, a recut version of Mel Gibson's The Passion of the Christ, which featured less violence than last year's original movie, took just $239,850 (�125,000), despite opening in 957 cinemas.

The new version of the film received little publicity and the original version is available across the US on DVD.

"We certainly had higher expectations than what we got," said Rob Schwartz, head of distribution for Newmarket Films, which released The Passion of the Christ.

"We were trying to get the film out there, hoping it would reach an audience that it didn't quite reach the first time around. It doesn't seem to have worked out quite as well as we had hoped."

Meanwhile, Will Smith comedy Hitch has become the top film at the global box office after taking an estimated $30.1m (�15.6m) over the weekend at cinemas outside North America, according to industry website Screen Daily.

It has taken $65.5m (�34.1m) so far, buoyed by opening at number one in the UK last weekend and a successful run in Germany.
