These Sherlock Holmes trailers just keep on coming, don’t they? An action-packed fourth one has appeared online over at MTV, and we have it here for your viewing pleasure. We’ve seen plenty of action in all the other trailers for the movie – including explosions, chases and hand-to-hand combat – but this latest trailer really turns up the action significantly.

Just as a reminder, Sherlock Holmes stars Robert Downey Jr. as the titular detective, and it co-stars Jude Law as his faithful assistant, Dr. Watson. Mark Strong plays the villain, Lord Blackwood and Rachel McAdams is the beautiful love interest, Irene Adler. Directed by Guy Ritchie (Snatch, Lock, Stock and Two Smoking Barrels), this fresh take on the classic detective character makes use of some things not seen in most Holmes tellings, namely his often-forgotten martial arts skills.

And now here’s the latest Sherlock Holmes trailer, courtesy of Trailer Addict (originating from MTV). Enjoy:

With the amount of action in that trailer, I’m just wondering how much is actually in the film. Have they used any and all of the action scenes in this trailer and thus we’ll have seen it all once the movie opens? Or is there so much action in the actual movie that what we see here in the trailer is just a taste of more to come? When it was revealed Ritchie would be directing, and that he would be taking the character in a fresher, more action-orientated direction, I didn’t expect the action to totally rule the film.

To me, one of the most important aspects of this new Sherlock Holmes (or any for that matter) is the “working” relationship between Holmes and Dr. Watson, which looks to have been nailed by Downey Jr. and Law. But if this trailer is anything to go by, the action is going to take precedent over everything else, and if that’s the case, then color me disappointed.

However, there’s always a chance that the studio is just releasing this action-packed trailer to get the audience it may not have snagged otherwise. After all, the other Holmes trailers didn’t go overboard with the action – here’s hoping the film is a great mixture of action and everything else, as it should be.

What do you think of the latest Sherlock Holmes trailer? Do you think the focus on action is just to get more people interested? Or is it the driving force of this movie?
