Sherlock Holmes 3 has been in development hell for 12 years, and following the announcement of Guy Ritchies newest project, I have no hopes for it ever happening. On January 8, 2009, Guy Ritchie brought Sherlock Holmes and Dr. John Watson back to the big screen, with Sherlock Holmes grossing $524 million at the box office. The film, which starred Robert Downey Jr. in the titular role and Jude Law as the famous sidekick, received a sequel three years later, Sherlock Holmes: A Game of Shadows.
