'Seven Psychopaths' debuts behind-the-scenes video - watch

Seven Psychopaths has debuted a behind-the-scenes featurette.

The video features interviews with stars Christopher Walken, Colin Farrell, Sam Rockwell and Woody Harrelson.



The actors discuss their on-set camaraderie while filming Martin McDonagh's black comedy.

Seven Psychopaths centres around struggling screenwriter Marty (Farrell) who finds himself knee-deep in trouble after his best friend Billy (Rockwell) and Billy's partner in crime (Walken) steal the Shih Tzu of a dangerous gangster (Harrelson).

The movie also stars Tom Waits, Abbie Cornish, Olga Kurylenko and Gabourey Sidibe.

It is McDonagh's first feature film since the Farrell-starring 2008 comedy In Bruges.

Seven Psychopaths will open on October 12 in the US and December 7 in the UK, and will also feature at the BFI London Film Festival.
