Will Ferrell and John C. Reilly have a new buddy comedy in the works. According to Deadline, Ferrell and Reilly have signed on to star in Sony’s Holmes & Watson, which is described as “inspired by the Arthur Conan Doyle’s Sherlock Holmes tale, but with a PG-13 comic bent similar to their past collaborations†with Ferrell playing Holmes and Reilly as Watson. Tropic Thunder and Idiocracy’s Etan Cohen wrote the script and will direct the film, which is slated to begin production later this year. Holmes & Watson has been in the works since 2008, when Ferrell was originally attached to star alongside Sacha Baron Cohen.
