(with a twangy, British accent) Right, boys, Martin McDonagh has made a new picture. Ai, the same Martin McDonagh who made “In Bruges,” with Colin Farrell. That was quite a spectacle, wasn’t it? Here’s the trailer for “Seven Psychopaths,” starring Colin Farrell, Sam Rockwell, Woody Harrelson, Christopher Walken and, Gabourey Siddibe–of course. If this triumphant cast doesn’t get your butt in the movie theatre, this trailer should. But first, a quick gander at the storyline of “Seven psychopaths”: a struggling screenwriter inadvertently becomes entangled in the Los Angeles criminal underworld after his oddball friends kidnap a gangster’s beloved Shih Tzu. So you’re either with me or without me.
