'Iron Man 2' tops weekend box office

Tony Stark piloted to the top of the box office but not the record books.

"Iron Man 2," the sequel starring Robert Downey Jr. as Marvel's gadget-happy billionaire superhero, earned $133.6 million domestically on its opening weekend, according to distributor Paramount Pictures' estimates Sunday. The opening rocketed past the original $98.6 million debut in 2008 and landed the record as the fifth-biggest opening weekend.

"We're thrilled with the combination of the way it's playing across the board," said Don Harris, Paramount's vice president of distribution. "It's playing as a fanboy movie, but it's also playing as family movie, too. I even know a bunch of people who are planning to take their mothers to see 'Iron Man 2' on Mother's Day, which really made me chuckle." "Iron Man 2" has taken in $194 million overseas since it debuted in many international markets last week, bringing its worldwide total to over $327 million. While Hollywood blockbusters typically open around the same date in most countries, some get an overseas jump of a week or more on their U.S. debuts. The biggest opening came from China with $7.3 million.
