Robin Williams, Ricky Gervais and Ben Stiller are laughing their way to the top of the U.S. box office - their new film NIGHT AT THE MUSEUM: BATTLE OF THE SMITHSONIAN has toppled the competition in its opening weekend (22-24May09).
The comedians co-star with Amy Adams, Owen Wilson and Hank Azaria in the film, which took in $53.5 million (£35.7 million) over the Memorial Day weekend.
The win was a shock for movie reviewers, who insisted Terminator Salvation - the fourth movie in the sci-fi franchise - was poised to take the top spot after scooping more than $13 million (£8.7 million) on its first day of release. But the film came in at second with $43 million (£28.7 million) in earnings.
The new Star Trek movie followed at third, with nearly $22 million (£14.7 million) in earnings and now boasting a three-week total of $183.6 million (£122.4 million).
Rounding out the top five are Tom Hanks' Angels & Demons and new comedy spoof Dance Flick, which took in $21.4 million (£14.3 million) and $11.1 million (£7.4 million) respectively.
