It doesn't take much detective work to find out that the cast and crew of Sherlock Holmes have landed in Williamsburg, Brooklyn. The film stars Robert Downey Jr., Rachel McAdams, and Jude Law, and they're all readying for their close-ups at the Marcy Avenue Armory at 355 Marcy Avenue, according to Filming in Brooklyn who notes the location is the same "where the interiors of Neville’s house were shot for I Am Legend." The NY Post even has some photographic evidence of the two male leads, and report back that "the Hollywood heavyweights were dressed in 19th-century period wear yesterday...Law sporting a distinguished mustache." The movie, which is actually set in London, is being directed by Guy Ritchie, but at least he's got the Williamsburg Bridge to separate him from his ex and A-Rod.
