Production on Iron Man 3 was temporarily shut down earlier today, after star Robert Downey Jr. was injured on the set. Take a look at Marvel Studios' official statement regarding the unfortunate incident.
"Robert Downey Jr. sustained an ankle injury on the set of Iron Man 3 in Wilmington, North Carolina while performing a stunt. There will be a short delay in the production schedule while he recuperates."
There are no specifics on what kind of ankle injury he sustained, although it does not seem to be serious. Production began in early June, with Shane Black directing from a screenplay he co-wrote with Drew Pearce.
