Brilliant detective Sherlock Holmes (Robert Downey Jr.) matches wits with the nefarious Professor Moriarty (Jared Harris) after uncovering a diabolical plot to destabilize the entire Western world in this sequel from director Guy Ritchie. A criminal mastermind without a conscience, Professor Moriarty is Holmes' worst nightmare -- a man who uses his incredible intellect for unspeakably evil purposes. When the Crown Prince of Austria dies and Inspector Lestrade (Eddie Marsan) rules the death a suicide, Holmes steps back to see the big picture. But little does Holmes realize that Professor Moriarty is about to commit a crime that will shock the entire world, and that solving it may be the death of him. Jude Law returns as Holmes' faithful sidekick Dr. Watson in a sequel also featuring The Girl With the Dragon Tattoo's Noomi Rapace and Rachel McAdams.
