Sherlock Holmes: A Game of Shadows still has two months until its release, yet Warner Bros. is already antsy to get a move on a third installation in Guy Richie’s Baker Street series. A deal is reportedly in the works with Drew Pearce, currently writing Iron Man 3, to pen the screenplay, which is sure to keep Robert Downey Jr. and Jude Law in their respective roles as Sherlock Holmes and Dr. Watson. Just depends whether No. 2 retroactively justifies a No. 3. [Deadline]
