EXCLUSIVE: Warner Bros has set Drew Pearce to write Sherlock Holmes 3, continuing the Guy Ritchie-directed series that stars Robert Downey Jr. and Jude Law. The deal will soon be sealed with Pearce, who is currently writing Iron Man 3, which will also star Downey.

This development comes even before the opening of the second installment of the franchise, Sherlock Holmes: A Game of Shadows, which bows December 16. The film focuses on the battle between Holmes, Watson, and their nemesis, Professor Moriarty. Jared Harris plays that role, and Noomi Rapace joins Rachel McAdams in the sequel. Pearce also did some writing on Pacific Rim, the big alien invasion film that Guillermo del Toro is about to begin shooting in Toronto for Legendary Pictures and Warner Bros. Pearce is repped by WME and Warren Dern.
