It looks like the movie was a big enough success that the second film will start shooting as early as July. This is really no surprise, Sherlock Holmes continues to do very well at the box office, consistently second behind Avatar every week since Christmas. The other big news for the sequel is that Brad Pitt will star. This was rumored a few times during filming of the first film, but now it's been confirmed that Pitt will be a part of the sequel. Looking good!
