The Sesame Workshop is suing the production company behind the upcoming Melissa McCarthy film, "The Happytime Murders," claiming they are doing irreparable harm to the storied brand with their R-rated movie.

According to court documents obtained by The Blast, the "Sesame Street" creators are taking issue with the film's tagline, "NO SESAME, ALL STREET."

They claim the trailer "deliberately confuses consumers into mistakenly believing that Sesame is associated with, has allowed, or has even endorsed or produced the movie and tarnishes Sesame’s brand."

Sesame claims the producers have "diluted and defiled Sesame’s beloved Sesame Street children’s television show." They describe the trailer for the film as being "explicit, profane, drug-using, misogynistic, violent, copulating, and even ejaculating puppets."

The film bills itself as "a filthy comedy set in the underbelly of Los Angeles where puppets and humans coexist." McCarthy plays a police detective who works with a puppet to solve the brutal murders of the former cast of a beloved classic puppet television show. Brian Henson directed the movie — he is the son of the legendary puppeteer, Jim Henson.

Sesame Workshop is suing STX Productions seeking to have all advertising for the film pulled ASAP. They are also seeking unspecified damages.
