This new Thai one-sheet for Jeremy Saulnier’s uber-violent Green Room (read our review) is pretty intense stuff, and I suspect you’d never see a giant knife and a pentagram on a theatrical poster here in the States.

Green Room is set for a New York and Los Angeles bow April 15th, with an expansion planned for April 22nd and Nationwide opening on April 29th, 2016.

The thriller is said to be a brilliantly crafted and wickedly fun horror-thriller starring Patrick Stewart as a diabolical club owner who squares off against an unsuspecting but resilient young punk band.

Anton Yelchin, Imogen Poots, Alia Shawkat, Joe Cole, Callum Turner, Mark Webber, Eric Edelstein, Macon Blair, and Kai Lennox also star.

“Down on their luck punk rockers The Ain’t Rights are finishing up a long and unsuccessful tour, and are about to call it quits when they get an unexpected booking at an isolated, run-down club deep in the backwoods of Oregon. What seems merely to be a third-rate gig escalates into something much more sinister when they witness an act of violence backstage that they weren’t meant to see. Now trapped backstage, they must face off against the club’s depraved owner, Darcy Banker (Stewart), a man who will do anything to protect the secrets of his nefarious enterprise. But while Darcy and his henchmen think the band will be easy to get rid of, The Ain’t Rights prove themselves much more cunning and capable than anyone expected, turning the tables on their unsuspecting captors and setting the stage for the ultimate life-or-death showdown.

Intense, emotional, and ingeniously twisted, GREEN ROOM is genre filmmaking at its best and most original. Saulnier continues to build his reputation as one of the most exciting and distinctive directors working today, with a movie that’s completely different from his previous, highly acclaimed Blue Ruin, but which is just as risk-taking and even more full of twists. The entire cast deliver first-rate performances, but Patrick Stewart gives a transformative and brilliantly devious turn as Darcy—elegant yet lethal, droll yet terrifying, Stewart makes the film simply unforgettable.”
