Iron Man 3 is keeping the pedal to the metal.
The Robert Downey Jr. sequel scored an estimated $15.6 million in its domestic debut, upping its worldwide total to a fast and furious $361 million.
Internationally, the film is already its franchise's top-grossing entry.
The movie's reported midnight Friday take, which, per the new Hollywood standard, includes business from Thursday preview screenings, is likewise an Iron Man best.
The 2008 original grossed a relatively mortal $1.5 million from midnight screenings; 2010's Iron Man 2 grew to $7.5 million, but was still a long way away from the all-time night-owl champs.
Iron Man 3 was no Harry Potter or Dark Knight itself, but it did put up an Avengers-comparable number—and it's never a bad thing to be on the heels of Hollywood's opening-weekend record-holder.
On the whole, Iron Man 3 is expected to be headed for a three-day weekend domestic gross north of $150 million.
