Woody Harrelson (Friends with Benefits), Olga Kurylenko (Centurion) and Tom Waits (Wristcutters, plus all the good things ever) have all joined Martin ‘In Bruges’ McDonagh’s new film Seven Psychopaths, which already stars Colin Farrell, Sam Rockwell and Christopher Walken.

As far as we can make out (keep up, this is mental), Farrell will play a struggling screenwriter working on his script Seven Psychopaths. His friends Rockwell and Walken are dognappers, and when Farrell inadvertently becomes involved in the kidnapping of a prize Shih Tzu belonging to a psychopathic gangster kingpin (Harrelson) shit goes down in no uncertain terms. And you thought Belgium was racy…

How mental, on a scale of one to mental, is this film going to be? You know the drill.
