Will Ferrell and John C. Reilly to play Sherlock Holmes and Dr Watson in new comedy

Will Ferrell and John C. Reilly are to team up once again for new comedy Holmes & Watson.

The pair, who have scored big hits when they teamed up in Talladega Nights and Step Brothers, will offer up a comic take on Arthur Conan Doyle's iconic detective and assistant. Ferrell will play Holmes with Reilly as Watson.

According to Deadline, the movie has been in development for several years with Sacha Baron Cohen originally slated to co-star alongside Ferrell, but has now been resurrected with Reilly. 

Etan Cohen, who directed 2015's Get Hard, as well as writing Tropic Thunder and Men In Black 3, is in the director's chair.
