Iron Man 2 has rocketed to the top of the box office chart to score the fifth biggest opening weekend in history with a powerful $133.6 million.
The sequel to the 2008 hit, starring Robert Downey, Jr. as the comic book superhero, dominated movie theatres this weekend (07-09May10) as the nation celebrated Mother’s Day on Sunday (09May10).
The bumper figures overshadowed the takings of the original Iron Man, which grossed $98.6 million when it debuted in 2008.
However the follow-up failed to match the record set by The Dark Knight in 2008, which holds the title for the biggest opening weekend ever at the box office with $158.4 million. Iron Man 2 sits behind Pirates of the Caribbean: Dead Man’s Chest in the record books – the Disney adventure is fourth on the list after taking $135.6 million upon its release in 2006.
Iron Man 2′s profits takes the Jon Favreau movie’s worldwide total to over $327 million.
Last week’s most popular film, a remake of A Nightmare on Elm Street, fell to second place with $9.1 million, while animated hit How to Train Your Dragon held strong at three with $6.7 million, more than a month after its release.
