Ben Henson, Jim Henson’s kids, and director of many Muppet movies, is being sued by Sesame Street over the marketing of his latest film, an R-rated cop movie with puppets:

Not everything is A-OK on Sesame Street today. The creators behind the beloved children’s show are suing STX Entertainment for the use of their brand name in the trailer and other marketing of the R-rated Muppets-inspired movie The Happytime Murders, according to Variety.

Both the trailer and the poster for the risqué project, directed by Jim Henson’s son Ben Henson, carries the tagline “No Sesame. All Street.” As such, the Sesame Street makers claim that this tarnishes their child-friendly brand, and they want all references to it completely Gonzo or else.

The film imagines a world where Muppet-like puppets get up to all manner of no good (the trailer contains drug use, foul language, and a pretty graphic puppet sex scene, watch below) with Melissa McCarthy playing a detective on the hunt for a serial killer who is intent on blowing the loveable creatures to pieces of fluff.

I am so going to see this movie.
