'Iron Man 3' is firmly back on track after Robert Downey Jr recovered from his ankle injury and returned to the set. Principal photography was halted on August 18, 2012, when the actor hurt himself while performing a minor stunt.

After taking a couple of weeks off, Downey Jr is back on his feet and resumed filming in Miami this week. A replica of the Malibu, California, seafood restaurant Neptune's Net was recreated for a sequence in the film, with some intrepid comic-book fans managing to take snaps and leak them online. According to Entertainment Weekly, the actual restaurant is a popular hangout for surfers and bikers, and as Tony Stark lives in Malibu, it's likely that the scene will see him grabbing a bite to eat before heading out to fight crime.

Despite the delays, Marvel insist Iron Man 3 remains on track for a May 3, 2013, release date, though it's likely that director Shane Black and his team will be working plenty of long nights to get it ready in time. Meanwhile, fans of the Iron Man series should mark their calendars as Marvel promises the first teaser trailer will debut at 12.01am on October 23, 2012.
