A new TV trailer has appeared online for Guy Ritchie’s Sherlock Holmes, which simultaneously stays true to the character source material as well as putting a fresh spin on it (in combining both, for example, Ritchie is implementing Holmes’ little known martial arts background).

The new trailer may look pretty similar to the previous ones we’ve seen (particularly the last international trailer), but in the last third it differs significantly, including showing us some new funny footage of Holmes experimenting on a dog. That’s all I’ll say (it’s not what it sounds like, I promise!).

Stepping into the shoes of Sherlock Holmes is Iron Man himself, Robert Downey Jr., who looks to have absolutely nailed the role (does he ever not?). Joining him is Jude Law as Holmes’ faithful sidekick, Dr. Watson, Mark Strong as the film’s villain, Lord Blackwood, and Rachel McAdams as love interest, Irene Adler. At first it seemed like a strange cast, but the more we see of the actors in their respective roles, the more I think Ritchie’s assembled cast is pretty much perfect.

SHERLOCK HOLMES TV TRAILER

More than the cast (particularly Downey Jr.), what surprised me most about this new Sherlock Holmes outing was the fact that Guy “Snatch and Lock, Stock and Two Smoking Barrels” Ritchie signed on to direct it. He’d be one of the last people I would have thought of if asked to name a list of directors who would take on the classic detective character. I’m definitely intrigued to see how he’s handled Holmes – the footage we’ve seen so far looks great, IMO – after working mostly in the funny-gangster-flick genre so far.

What do you think of the latest Sherlock Holmes trailer? Are you looking forward to this movie, particularly with the cast and director it has?
