Sherlock Holmes: the Hound of the Baskervilles made in 2002 starring Richard Roxburgh and the fantastic Richard E. Grant, starting with part 1 link here.
I also previously mentioned the 2004 version of Sherlock Holmes: Case of the Silk Stocking starring Rupert Everett, Michael Fassbender, and Honeysuckle Weeks (Foyle's War) sibling Perdita Weeks. Here's a sneak peak. If you want it... your local library will likely have it... or you may have to fork out the cash.
