Iron Man might be invincible but actor Robert Downey Jr. is far from it. The 47-year-old actor injured his ankle while filming Iron Man 3 on Wednesday.

"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," Marvel Studios said in a statement.

The third installment of the superhero franchise is currently scheduled for a May 3, 2013 release and stars Ben Kingsley, Gwyneth Paltrow, Don Cheadle, Guy Pearce and Rebecca Hall.
