Hitting theaters in exactly one month, Martin McDonagh's Seven Psychopaths appears to have launched a viral campaign with the Twitter account @PsychoCostello, based on Woody Harrelson's ganster character, Charlie Costello. He's posted the below flyer with information about his missing Shih Tzu, Bonny, and you can call (323) 989 2669 to hear an in-character phone message.

The film follows a struggling screenwriter (Colin Farrell) who inadvertently becomes entangled in the Los Angeles criminal underworld after his oddball friends (Christopher Walken and Sam Rockwell) kidnap a Costello's dog.

Opening in theaters on October 12, the R-rated comedy also stars Abbie Cornish, Tom Waits, Olga Kurylenko and Zeljko Ivanek.
