Sherlock Holmes: A Game of Shadows is set for release December 16, 2011, and seeing as only one trailer had been released so far, it definitely was time a second one.
Where the first trailer back in July seemed to be more about focusing on the action aspects of the film, this one seems to be much more centered around the concept that Holmes will be going up against his most well-known enemy, Professor Moriarty. Beyond that, it definitely looks like Robert Downey Jr. is again playing Holmes as someone walking a very thin line between brilliance and complete psychosis … and it totally works.
Although I’d love to hear why Guy Ritchie went so nuts with the slow motion of exploding trees …
