Speaking of the Man in the Iron Suit, it appears that Iron Man star Robert Downey Jr. injured his foot during a stunt on set. According to Disney:
While performing a stunt on the set of Iron Man 3, Robert Downey Jr. sustained an injury to his foot. There will be a short delay in production while he recuperates.
Nothing else is known at this point. This comes on the heels of actress Mayim Bialik (The Big Bang Theory) who suffered injuries to her hand in an automobile collision in New York City yesterday. Fortunately she tweeted yesterday (with her husband typing) that she was “in pain but will keep all my fingers,” and she was back on set today.
