Get ready for dueling Sherlock Holmes films, including a comic take starring Sacha Baron Cohen and Will Ferrell.

According to Variety, the Sherlock Holmes comedy is set up at Columbia Pictures with Etan Cohen ("Tropic Thunder") scripting for producers Judd Apatow and Jimmy Miller.

The Apatow-produced Holmes pic will feature Cohen as Arthur Conan Doyle's famous London gumshoe and Will Ferrell as his trusty partner Watson, reuniting the two "Talladega Nights" co-stars.

This project should in no way be confused with Warner Brothers' more action-oriented Sherlock Holmes feature, which is expected to be directed by Guy Ritchie from a script by Anthony Peckham.

Doyle introduced the Victorian sleuth in the story "A Study in Scarlet." The author featured the character in four novels and 56 short stories.

Well over a dozen actors who have played the Holmes character on the big and small screen, a group that includes Peter Cushing, Rupert Everett, Ronald Howard, Jeremy Brett, Christopher Lee, Robert Stephens and, perhaps most iconically, Basil Rathbone.

Cohen will next be seen in next summer's "Bruno."

Ferrell has "Step Brothers" coming out later this summer and recently completed production on "Land of the Lost."
