On the first Sherlock, we kind of introduced a little bit of a new take on Sherlocks fighting style and its been fun to bring that to the next level, he told Access Hollywood over the weekend, of the martial arts employed in the film, due in theaters on December 16. Also, Guys (Ritchie) directing style. I think whats not boring about it to me is that theres new camera techniques and theres a lot of thought behind it, he added. Its not just a bunch of fight moves, you know. The actor stays in shape for roles like Sherlock and Iron Man, and he confirmed that after Tropic Thunder, his wife Sherlock producer Susan Downey helped inspire him to get fit. She told me I had turned into a bit of a slob, he revealed. I blame it on Bubbas Burgers. Probably one of the great burger establishments known to mankind. While a weight comment can be tough for some to hear, Robert thought it over and decided he agreed with Susan. As usual, I looked at her like, All right, shes got some warped perception of whats going on here, and then when I realized that I couldnt fit into any of my clothes, I honestly thought maybe because Id been in a different climate that theyd all shrunk, and then eventually I came around.
