According to ComingSoon.net, Marvel Studio has released an official statement confirming that Robert Downey Jr has sustained an on-set injury, temporarily halting Iron Man 3‘s production.
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.
Hopefully by “short delay,” Marvel is implying that the ankle injury isn’t too serious. In any case, RDJ Fan sends Robert good vibes and hopes for a speedy, safe, and happy recovery.
