This is no Sesame Street. STXfilms has released the red band trailer for The Happytime Murders, a raunchy R-rated puppet movie starring Melissa McCarthy. (Yes, puppets have sex in this movie.)

Per its logline, The Happytime Murders is a filthy comedy set in the underbelly of Los Angeles where puppets and humans coexist. Two clashing detectives with a shared secret, one human (McCarthy) and one puppet, are forced to work together again to solve the brutal murders of the former cast of a beloved classic puppet television show.

Directed by Brian Henson, puppeteer, son of Muppets creator and master puppeteer Jim Henson and current chair of The Jim Henson Company, The Happytime Murders also stars Maya Rudolph, Joel McHale and Elizabeth Banks.

Henson, McCarthy, Jeffrey Hayes and Ben Falcone serve as Happytime producers, while Lisa Henson, Dee Robertson and John W. Hyde executive produce. McCarthy and Falcone produce under their On the Day Productions banner.

The story is by Todd Berger & Dee Robertson; the screenplay is by Berger. STXfilms VP Production Sheroum Kim and creative executive Kate Vorhoff oversaw the production.

The Happytime Murders hits theaters August 17.
