Surprising no one but pleasing audiences, X-Men Origins: Wolverine topped the weekend U.S. movie box office with a heroic opening-weekend total of $87 million in the United States and Canada and $160 million worldwide. The movie cost approximately $130 million to produce.

Wolverine led a strong first weekend of Hollywood’s "summer" season of popcorn movies, with the rest of the top ten dominated by genre films such as comedies and action fare. 

Last year’s top-grossing film, Iron Man, brought in $98.6 million during its first weekend in U.S. and Canadian theaters.
