In what might be the greatest comedy of all-time (am I jumping ahead of myself?), Will Ferrell shall be the sidekick for Sasha Baron Cohen takes the lead as Sherlock Holmes. Ferrell will be his Watson in a comedy about the master detective. Etan Cohen (Tropic Thunder) is writing the screenplay and Judd Apatow will produce.
This is the second Sherlock film that is underway with Guy Ritchie attempting a more serious film.
