Brad Pitt won’t be joining the cast of Guy Ritchie’s Sherlock Holmes after all.

London’s Daily Mirror reported that he is set to arrive in London this week to begin filming scenes as Holmes’ nemesis Moriarty. He is expected to shoot all over the city, including the Royal Victoria Dock, Pontoon Docks, Pinewood and Chatham Docks in Kent, the paper claimed.

Ritchie – who last worked with Pitt in 2000′s Snatch – decided to add Pitt to the cast, which includes Robert Downey Jr as Holmes and Jude Law as Dr. Watson – after seeing the first edit, according to the report.

But a studio rep tells Us: “The report in today’s London Mirror is completely inaccurate. Brad Pitt is not joining the cast of Sherlock Holmes and we’re extremely pleased with the production of the film. As planned, it will be released on Christmas Day, 2009. In order to complete the movie, we’ve scheduled a few days on set to shoot a couple of additional scenes, obtain pick-up shots, and perfect some of the visual effects elements, all of which is standard filmmaking practice.”
