Muppet Noir?

Henson's Muppets set for Happytime Murders...

Brian Henson, son of the late Jim Jenson, is moving forward with a project that will plant muppets into the film noir world for a new movie called Happytime Murders. The movie will mix muppets and real people, be aimed at adults, and be about a detective investigating a string of murders involving the cast of a children's show called the Happytime Gang.
