Charlie Sheen is still sparring with Warner Bros. The studio issued Sheen a cease and desist letter demanding he stop using photos from his days of Two and a Half Men to promote his upcoming FX sitcom, Anger Management.

The Hollywood Reporter said that at least two snaps of the actor from the Men set were included in a promotional publication that Sheen and his partners used to pitch their show at the NATPE conference in Miami last month.

A lawyer for Warner Bros. wrote in the letter, “That you are using Warner’s intellectual property for a commercial purpose — namely, to sell another show — is especially egregious. Please immediately cease and desist from using these photographs or any other intellectual property belonging to Warner.”
