Iron Man 3 is continuing to destroy the U.S. box office after raking in $72.5 million (£46.78 million) in its second week on release.

The blockbuster, featuring Robert Downey, Jr. as the comic book superhero, drew a staggering $175.3 million (£113 million) to score the second highest-grossing opening weekend in U.S. history last week (ends05May13) and it's still proving to be a big draw - the film has now banked a whopping $949 million (£612.3 million) worldwide.

Iron Man's domination prevented The Great Gatsby from reaching number one on the chart - Baz Luhrmann's adaptation of the classic F. Scott Fitzgerald novel, starring Leonardo DiCaprio, debuted in second place with a strong $51.1 million (£32.97 million).
