The Great Sherlock Holmes is such a distinguished character much like Hercule Poirot, Miss Marple, Magnum and Sam Spade, Nancy Drew....the list goes on!!! The "pursuit for...the truth continues"; it is never ending. There was an episode of Holmes on Homes where Mike Holmes did a fantastic job (big surprise), of fixing this elderly couple's house and they gave him, I believe, one or two volumes of the complete works of Sherlock Holmes because they felt he possessed some of the same qualities. That was my favorite episode.
There is a cartoon called "Sherlock Holmes in the 22nd Century" and I must say, it's quite good. The voice for Holmes, (Jason Gray-Standford), does a lovely British accent. What's funny is that the Chief Inspector Lestrade is a woman, the ancestor to the Lestrade Holmes knew in the 1800s. Power to the Woman!!!
Jeremy Brett is, in my opinion, the definitive Sherlock Holmes. R.I.P. Jeremy Brett.
I've only seen the trailers for the Robert Downey Jr. version and I have to say that I don't like it. Holmes was not like that in the books. Anyways, that's only me. He is a good actor as well as Jude Law.
