Will Ferrell And John C. Reilly Will Sing Each Other Love Songs In A Sherlock Musical

There’s nothing elementary about a crime-fighting love song

In Step Brothers, the 2008 comedy that paired Will Ferrell and John C. Reilly as reluctant siblings, the guys set about building bunk beds so that they could fully maximize their new shared room. They knew zilch about construction or how to work a drill, clearly, but they somehow got one bed on top of another, which freed up the floor space for "so many activities" for them to do and, uh, accidents for them to have.

Think of Ferrell and Reilly's forthcoming Sherlock Holmes movie as that, except their activities will involve music and choreography, potentially.

According to The Hollywood Reporter, Holmes & Watson — a comedic retelling of the English investigative duo — is on the way starring Ferrell and Reilly, and featuring two original songs sung written by Alan Menken. Menken is the man behind a ton of memorable Disney ballads, from The Little Mermaid's "Part of Your World" to Tangled's "I See the Light," and he and lyricist Glenn Slater have written two songs for the flick, including a love song between the detective and his partner in solving crime.

“It begins in a musical theater, almost Rex Harrison kind of a way, and then it turns into a full-on '70s pop/soft-rock love extravaganza, with an operatic interlude in the middle," Slater tells THR. "It’s a bizarre hodgepodge.”

Ferrell and Reilly doing something bizarre?! Nahhhh. Hopefully they sing better than they build beds, though.

Holmes & Watson is set to hit theaters in 2018. Etan Cohen has written the script and will direct, and this follows up his last project with Ferrell, Get Hard, which he also wrote and directed.
