There are some great comedic duos in the modern age of cinema, but there are few that rival the love and success that Will Ferrell and John C. Reilly have managed to obtain. The pair have been wanting to team up again for quite some time, and they finally are. It isn't for a Step Brothers sequel though, as one might expect. Ferrell and Reilly will be taking on the classic duo of Sherlock Holmes and John Watson with the new movie Holmes & Watson.

The news comes courtesy of Deadline and reveals that the new movie is happening over at Sony Pictures. Holmes & Watson is said to be taking on the characters made famous by Sir Arthur Conan Doyle, but will be putting a PG-13 comedic spin on it. Ferrell will be re-teaming with another recent collaborator, as the report also notes that Etan Cohen will be directing the movie, who directed Get Hard last year.

Will Ferrell will be playing the role of Sherlock Holmes in the movie, and John C. Reilly will be taking on the part of his faithful sidekick John Watson. The project has reportedly been in development for quite some time, and originally had Sacha Baron Cohen attached instead of Reilly. It reportedly stalled, and eventually Cohen moved on. According to Deadline, once Reilly got on board, the project came back together very quickly over the last few weeks. Now Sony is very motivated to get it going, and since everyone is available, Holmes & Watson will be heading into production this fall just after Thanksgiving.

The comedic pair of John C. Reilly and Will Ferrell first teamed up ten years ago for Talladega Nights: The Ballad of Ricky Bobby. The movie did pretty well at the box office, bringing in just shy of $163 million worldwide, but it fared very well with fans and critics and found a large audience over the years. The pair had another hit in 2008 with Step Brothers, which was directed by Adam McKay. The movie brought in $128 million worldwide, and fans have been wanting them to team up again ever since. Many likely didn't picture that team up as being a Sherlock Holmes movie, but that is the case.

For one reason or another, not the least of which is that the Sherlock Holmes works are in the public domain, there are a lot of various projects involving the famous detective currently happening. BBC's hit show Sherlock is currently filming its fourth season, and there have been persistent reports that Guy Ritchie will be making a follow up to Sherlock Holmes: A Game of Shadows with Robert Downey Jr. and Jude Law. In addition, CBS is airing a new season of Elementary in October, and Sir Ian McKellen starred as an older version of the character in Mr. Holmes last year. There is no word yet on an anticipated release date for Holmes & Watson.
