This is the Dolby Buzz. From now, right through December, we will be bringing you an exclusive behind the scenes look at Warner Bros new epic action adventure film, Sherlock Holmes, starring Robert Downey Jnr. Over the next month we will be speaking with the cast, catch up with Director Guy Ritchie and discover what it takes to bring this epic adventure to the big screen.
