‘Iron Man 3’ breaks $1 billion at box office worldwide

But Robert Downey Jr still hasn't decided whether he wants to make 'Iron Man 4'

Iron Man 3 has now grossed more than $1 billion (£650 million) worldwide.

As of yesterday (May 19), the superhero sequel has earned $337 million at US cinemas and $698 million internationally for a global total of $1.035 billion (£670 million), according to Box Office Mojo.

This puts it comfortably ahead of the first Iron Man film, which grossed $585 million (£380 million) in 2008, and 2011’s Iron Man 2, which raked in $623 million (£405 million) two years later.

In fact, since its release on April 25, Iron Man 3 has already become the 15th highest-grossing film ever – and it’s likely to climb higher. Last year’s The Avengers, which also featured Robert Downey Jr as Tony Stark, is third on the all-time list with takings in excess of $1.5 billion (£980 million).

At present, Downey Jr has yet to decide whether he wants to make another standalone Iron Man film, though he’s apparently in negotiations to reprise his role as Tony Stark in two more The Avengers movies. The Avengers 2 is set for release in May 2015.
