"Brand was snapped arriving at the director’s London home yesterday morning to discuss whether he would have a role in Ritchie’s upcoming film Sherlock Holmes 2."
The website also scored some pictures of Russel arriving at director Guy Richie's House
Now with casting in full swing it could be perfectly reasonable for Brand to score himself a role, But as there is no official confirmation as to whether Brand has landed a role this could turn out to be false. There was no mention as to what character Brand would play.
So that being said Russel Brand may join the cast of Robert Downey Jr, Jude Law, Noomi Rapace, and Jared Harris
