We spotted Rachel McAdams sporting a very old timey hairdo in New York City yesterday, but that’s probably because she was on the set of Sherlock Holmes!  Rachel was joined by her co-stars, Robert Downey Jr. (Sherlock Holmes) and Jude Law (Dr. Watson).  Both Rachel and Jude had small cuts on their faces, hope that was just stage make up!  The Guy Ritchie-directed Sherlock Holmes will come out some time in 2010.
