Iron Man reigns as the standard-bearer of Hollywood superheroes with a $175.3 million domestic opening weekend for his latest sequel, The Associated Press reported.
According to studio estimates Sunday, "Iron Man 3" raced to a worldwide total of $680.1 million. That includes $175.9 million in its second weekend overseas, where the film has rung up $504.8 million so far.
No other solo superhero -- not even Batman or Spider-Man -- has managed this kind of business.
Yet "Iron Man 3" hints that Robert Downey Jr.'s Tony Stark might hang up his high-tech suits and live a normal life from now on. As the centerpiece behind not only the "Iron Man" flicks but also Marvel's superhero ensemble "The Avengers," Downey seems crucial to this comic-book world.
