Even though he's just released RocknRolla, Guy Ritchie is hard at work on his next project.  We spotted Guy and Robert Downy Jr. filming a new screen adaption of Sir Author Conan Doyle's Sherlock Holmes.

Currently shooting in London, Robert will play the titular character with Jude Law as his sidekick Dr. Watson and Rachel McAdams as Holmes' love interest, Mary.

Robert told the Guardian that Guy was taking on the story in an innovative way (in comparison to previous versions), "[we're] returning to a little bit more of what the stories always had in them and the scale of them and the canvas is so huge I just don't think they've ever had the budget to fully tell the story in a really big, fun way."  Guy Ritchie added, "We're trying to be as authentic as we can to the original Sherlock Holmes. We've tried to include a bit more Conan Doyle in it."

Expect the newest Sherlock Holmes out sometime next year.  Click through the gallery to see a very Charlie Chaplin-esque RDJ doing his thing on set.
