We first showed you the new theatrical poster for Warner Bros’s upcoming “Sherlock Holmes: A Game of Shadows” yesterday. Today we have the first official trailer for the Guy Richie sequel starring Robert Downey Jr., Jude Law, Noomi Rapace, Stephen Fry and Jared Harris. The sequel looks like it’s going to be a lot of fun and may be even more action-packed than the first which, while it didn’t blow me away, had me entertained.

Here’s the official film synopsis:
Robert Downey Jr. reprises his role as the world’s most famous detective, Sherlock Holmes, and Jude Law returns as his formidable 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 Moriarty (Jared Harris)—and not only is he Holmes’ intellectual equal, but his capacity for evil, coupled with a complete lack of conscience, may actually give him an advantage over the renowned detective. When the Crown Prince of Austria is found dead, the evidence, as construed by Inspector Lestrade (Eddie Marsan), points to suicide. But Sherlock Holmes deduces that the prince has been the victim of murder—a murder that is only one piece of a larger and much more portentous puzzle, designed by one Professor Moriarty.

“Sherlock Holmes: A Game of Shadows” comes out on December 16, 2011.
