Here's an interesting counterpart to the most recent cinematic excursion into Holmesiana: the first episode of a famous Russian TV adaptation of the stories, starring Vasili Livanov and the late Vitali Solomin. (The poster has also put up two more installments.) The script combines A Study in Scarlet with "The Speckled Band," complete with a moment of meta-snake snark at the end. Although it's a little odd to see an obviously middle-aged Holmes paired with a much younger Watson--at the time, Livanov was in his early fifties, and Solomin in his late thirties--the two actors have a strong rapport. Livanov is more in the Rathbone mode, both in looks and performance; his Holmes is eccentric and clearly egotistical, but also charismatic. Solomin's Watson, meanwhile, hews quite close to ACD's original--despite the wound, he's an athletic sharpshooter--albeit with a more pronounced sense of humor. (The writer makes a point of noting Watson's affinity for fiction: there's obviously a budding writer in there somewhere.)
The poster has done his or her own subtitling into literal English, occasionally with odd results, but you can certainly get the gist of the dialogue. Note that episode #2, which I've linked, is actually episode #1.
