Well, now, Sherlock went out and got his hands dirty. He was an expert in the martial art of bartitsu, and Watson said that he saw Holmes beat McMurdo (the guy he's fighting there in the pit) in a boxing match. It wasn't all pipes and drawing rooms and deerstalker hats.

And Doyle wouldn't actually care:

When William Gillette was considering how to approach writing a Sherlock Holmes play, he thought it well to provide a love interest for Holmes. Audiences loved romance.

Gillette wired Doyle for his permission: "May I marry Holmes?"

Doyle responded, "You may marry, or murder, or do what you like with him."

And I have full faith and confidence that the movie will be splendid. Whether it collides with The Canon or slides into it. :)
