Jeremy Saulnier rocked the world in 2013 with Blue Ruin, an indie darling he and his family poured their savings into, along with some help from a successful Kickstarter campaign. Their efforts paid off with a premiere at the Cannes Film Festival, a spot on numerous critics’ Top 10 lists, and a whopping 96 percent on Rotten Tomatoes. Now, Saulnier has returned with Green Room, a horror-thriller about a punk band trapped by a backwoods white supremacist group after a murder occurs backstage during a show.

The film stars Anton Yelchin (Star Trek), Imogen Poots (Fright Night, Knight of Cups), Alia Shawkat (The Final Girls), Mark Webber (Scott Pilgrim vs. the World), and Patrick Stewart as the leader of the supremacists, a role so removed from his usual image. The film already debuted at the Cannes Film Festival, but will enjoy a limited release on April 1 before a wider release on April 15.

The trailer, embedded below, is pretty damn savage. There’s that one moment you see the arm torn out of the socket in an arm bar — not even The Raid has that kind of delicate madness.

Saulnier might have avoided a sophomore slump in this fresh take on the backwoods horror genre; Green Room currently scores at 92 percent on Rotten Tomatoes.
