Robert Downey Jr. reprises his role as the world's most famous detective, Sherlock Holmes, and Jude Law returns as his friend and colleague, Dr. Watson, in Sherlock Holmes: A Game of Shadows. Sherlock Holmes has always been the smartest man in the room...until now. There is a new criminal mastermind at large-Professor James Moriarty (Jared Harris)-and not only is he Holmes' intellectual equal, but his capacity for evil, coupled with a complete lack of conscience, may give him an advantage over the renowned detective.
