Robert Downey Jr. reportedly had to get six stitches in his mouth on set of his latest film Sherlock Holmes. The Iron Man actor was filming a fight scene with seven foot tall co-star Robert Maillet when the big man threw a punch that left Downey Jr. “out cold.” A nurse on set attended to the actor and said that it is not critical. After a two weeks the stitches will be gone, no marks. Robert Downey Jr. thinks that he is still the ironman in the movie where things won't hurt him. It will be very dangerous if he takes the role as superman in the movie. Producers beware!
