Two and a half years ago, Guy Ritchie revived the classic Sherlock Holmes stories of Sir Arthur Conan Doyle, starring Iron Man himself as the eccentric detective. This past Christmas, he also directed the sequel of the film, in the wake of the BBC’s brilliant Sherlock series. Now that sequel Sherlock Holmes: A Game of Shadows is available on Blu-ray and DVD. Whether you like these new films or you prefer the BBC show, you can enjoy the new movie with this drinking game of shadows. Of course, if you want to start things off right, you can also enjoy Guy Ritchie’s original Sherlock Holmes with a few drinks here. Though we don’t recommend using formaldehyde as your spirit of choice, as Holmes does in the movie. That would kill you dead faster than Lucy Liu’s upcoming Elementary television series.
