Studio ramps up development on third film. Warner Bros. is wasting no time in moving ahead with a third ‘Sherlock Holmes.’ The first sequel, ‘Sherlock Holmes: A Game of Shadows’ is two months away from release, and now both Deadline and Variety are reporting that the studio has set scribe Drew Pearce to pen the third installment of the Guy Ritchie-directed series that stars Robert Downey Jr. and Jude Law. Pearce, a British TV writer-producer, is currently working away on a script for ‘Iron Man 3’ for director Shane Black. He is also penning a script for an adaptation of the DC Comic title ‘The Mighty,’ and has worked on Guillermo del Toro’s alien invasion epic ‘Pacific Rim.’ The studio employed a similar tactic two years ago, when it hired Kieran and Michele Mulroney to pen the screenplay for ‘Sherlock Holmes: A Game of Shadows’ three months before the first movie bowed at cinemas. ‘Sherlock Holmes: A Game of Shadows’ opens in cinemas December 2011.
