Shooting of the movie Sherlock Holmes 2 will indeed start this summer. Robert Downey Jr and Jude Law will be back respectively as Sherlock Holmes and Dr Watson. And Director Guy Ritchie will most likely helm this movie sequel to Sherlock Holmes.
The plot of Sherlock Holmes 2 hasn’t been announced yet, but I guess Professor Moriarty, the shadow of the first film, will be the main villain of the sequel. According to the rumor Actor Brad Pitt may play the role of Moriarty.
