Jude Law as Watson and Robert Downey Junior as Sherlock Holmes
Just take a look at this trailer. What a marvellous, steampunk vision of London, with Holmes as we've never seen him before. I may well have a fit of the vapours!
But, for those who prefer a more traditional Victorian rendition of Conan Doyle's famous character, I don't think the actor Jeremy Brett has ever been surpassed in his television portrayal of Holmes. I have to thank another Victorian sleuth, the splendid Lord Likely (http://www.lordlikely.com/) who reminded me of this video clip in which Holmes demonstrates the Queensbury rules of boxing. Watch out for that fancy footwork and those whirling windmill fists!
Here he is inspecting The Blue Carbuncle - the subject of a short story first published in the Strand Magazine in 1892.
