A new featurette for Sherlock Holmes: A Game of Shadows has gone online. The featurette gets into the plot a bit, which is good because I still have no idea what the film is about after two trailers. We also see some new footage, and more of Rachel McAdams' return. I love the cast and I love the idea of Sherlock Holmes going up against the formidable Moriarty, but I’m still a bit unsold on the film as a whole based on what we’ve seen so far. Granted, we’ve only seen roughly 5 minutes of smash-cut footage so we can’t really make a fair judgment just yet, but it looks like too much of the same which could lead to a sequel more along the lines of The Hangover 2 than The Dark Knight. Hopefully director Guy Ritchie has a few surprises up his sleeve.

Hit the jump to watch the featurette. The film stars Robert Downey Jr., Jude Law, Jared Harris, and Noomi Rapace. Sherlock Holmes: A Game of Shadows opens December 16th.

Here’s the official synopsis for Sherlock Holmes: A Game of Shadows:

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. Mixing business with pleasure, Holmes tracks the clues to an underground gentlemen’s club, where he and his brother, Mycroft Holmes (Stephen Fry) are toasting Dr. Watson on his last night of bachelorhood. It is there that Holmes encounters Sim (Noomi Rapace), a Gypsy fortune teller, who sees more than she is telling and whose unwitting involvement in the prince’s murder makes her the killer’s next target. Holmes barely manages to save her life and, in return, she reluctantly agrees to help him. The investigation becomes ever more dangerous as it leads Holmes, Watson and Sim across the continent, from England to France to Germany and finally to Switzerland. But the cunning Moriarty is always one step ahead as he spins a web of death and destruction–all part of a greater plan that, if he succeeds, will change the course of history.
