Overall, the Box Office was up 44.3% on last weekend's total gross.

The US summer box office season kicked off in earnest with a big return from its first blockbuster, X-MEN ORIGINS: WOLVERINE. The fourth film in the franchise earned a fantastic $85M over the weekend. Although its predecessor X-MEN: THE LAST STAND earned substantially more over its first weekend, this has to be seen as a big win for Fox considering how the last film left a bad taste in the audience's mouth and that this instalment, although slightly better received, is not doing much better in that department. The film will turn a profit thanks to this huge opening weekend, but look for X-MEN ORIGINS: WOLVERINE to have a healthy drop next weekend before quickly dropping out of the top 10.

Landing in a distant second is the Matthew McConaughy-Jennifer Garner romantic comedy GHOSTS OF GIRLFRIENDS PAST which had to settle for a much smaller $15.4M over the weekend. From all accounts the film is less than average and this one will likely suffer in a big way once more blockbusters appear over the coming weeks.

The Beyonce-Knowles thriller OBSESSED surprisingly still held well in its second weekend, earning $12M. The film has earned an impressive $46.8M since opening, all against a tiny $20M budget.

MONSTERS VS ALIENS finally recouped its $175M budget back this week, earning $5.6M over the weekend to take its total box office to a healthy $182M. The film will still likely do well over the coming weeks but will have to make room for the big films coming throughout the rest of May.

The only other new opener in the top 12 is BATTLE FOR TERA, which earned a little over $1M. This is as far up the box office chain as this Lionsgate animated flick will get.

The US Box Office took in a total of $150,419,035 for the whole of the weekend 1-3 May 2009.
