Robert Downey Jr: Back to Work on "Sherlock Holmes 2"

Hard at work on set for a re-shoot of “Sherlock Holmes: A Game of Shadows,” Robert Downey Jr was spotted filming in Greenwhich, London on Friday (September 23).

Sporting a fake wound on the side of his face, the “Due Date” stud sipped on coffee in between takes and shared a few laughs with the crew members.

Yesterday, Rob donned a traditional Chinese robe, a long braided ponytail and some interesting facial hair as he dressed in disguise for his role as Sherlock Holmes.

Co-star, Rachel McAdams who plays Irene Adler, was on-hand as well for the filming of the upcoming flick due out December 16th.
