Brad Pitt for Sherlock Holmes Sequel?

Guy Ritchie is keen to sign up Brad Pitt to star in the sequel to Sherlock Holmes, according to reports.

The director, who worked alongside Pitt in 2000's Snatch, was rumoured to have considered the actor for a cameo role in the new big screen adaptation of the famous detective stories.

But Ritchie is now thought to be eyeing Pitt for the role of Holmes' arch enemy Professor Moriarty in the follow-up movie.

Jude Law and Robert Downey Jr. have both reportedly already signed up for the second installment.

A source tells PopEater.com, "The director, Guy Ritchie, loves Brad. He has worked with him before and thinks he is one of the most underrated actors working today. Guy knows that everyone thinks of as a Pitt as a pretty boy and can't wait to turn him into the world's greatest supervillain. It will definitely make the sequel a must-see."
