Not completely. The Soviet Union did adapt a lot of classic literature alongside the more obvious Communist propaganda you'd expect. I think they used the old town of Riga in Latvia to film the London scenes. I have heard that the Russians still show these films every Christmas.

There are subtitled versions available online. Here is a short clip (with Sarabande over it)

I am a great fan of Brett's version, which I think is the best ever made. But I think the Soviet version is fantastic, considering it was made behind the Iron Curtain. There have, of course, been some awful Sherlock Holmes films but that's another matter.
