Here's Your First Look at Jared Harris as Moriarty in Sherlock Holmes: A Game of Shadows

As soon as Movieline heard that Mad Men's Jared Harris would be playing Sherlock Holmes's archenemy Moriarty in Guy Ritchie's Sherlock sequel A Game of Shadows, we were intrigued. After all, how would the Sterling Cooper taskmaster stack up against the long line of actors who have played Sir Arthur Conan Doyle's criminal mastermind -- including Laurence Olivier, Orson Welles, Henry Daniell, Paul Freeman and Vincent D'Donofrio? We may not have the answer just yet but we do have the first image of Harris as the "Napoleon of Crime."

Head over to USA Today to see some more pics, including new ones of Robert Downey Jr., Jude Law and Noomi Rapace. The Guy Ritchie-directed sequel arrives in theaters Dec. 16, 2011.
