Green Room is a 2015 American horror-thriller film[5][6] written and directed by Jeremy Saulnier, and produced by Neil Kopp, Victor Moyers and Anish Savjani.

Starring Anton Yelchin, Imogen Poots, Alia Shawkat, Joe Cole, Callum Turner and Patrick Stewart, the film focuses on a punk band who find themselves attacked by neo-Nazi skinheads after witnessing a murder at a remote club in the Pacific Northwest.

Pat, Sam, Reece and Tiger are members of a punk band, the Ain't Rights, travelling through the Pacific Northwest.

After their gig is cancelled, a local radio host, Tad, arranges a show through his cousin, Daniel, at a neo-Nazi skinhead bar in the woods outside Portland, opening for the Nazi metal band Cowcatcher.

Pat calls the police, but the bar employees Gabe and Big Justin confiscate the band's phones and hold them captive in the green room.

[12] On October 16, Anton Yelchin and Imogen Poots joined the lead cast of the film, along with Alia Shawkat, Callum Turner, Joe Cole, Macon Blair and Mark Webber.

[18] Saulnier, who used to play in a hardcore punk band called No Turn on Fred,[19] wanted the film to "stand the test of real musicians scrutinizing every frame".

[20] He enlisted Hutch Harris of American indie rock band The Thermals to teach the actors the musical parts that they would be performing onscreen.

[22] In addition to the songs appearing on the soundtrack, Green Room features several other punk and metal tracks, including Fear's "Legalize Drugs" (1995), Napalm Death's "Suffer the Children" (1990), Obituary's "Paralyzed with Fear" (2014), Poison Idea's "Taken By Surprise" (1990), Slayer's "War Ensemble" (1990), and Bad Brains' "Right Brigade" (1982).

[29] The end credits of the film's home media and subsequent releases feature an addended dedication to the memory of star Yelchin, who died on June 19, 2016.

The site's critical consensus reads: "Green Room delivers unapologetic genre thrills with uncommon intelligence and powerfully acted élan.

[33] Barry Hertz of The Globe and Mail awarded it a full four stars and wrote, "Jeremy Saulnier (Murder Party, Blue Ruin) continues one of the best streaks in independent horror with this terrifying and inventive thriller.

But scrape off the scum, and you’ll find Green Room full of visual artistry, dark humor, smart writing, and glints of humanity".

[35] IGN awarded it a score of 9 out of 10, saying, "This follow-up to the brilliant Blue Ruin pits a rock band against white supremacists with ace, ultra-violent results.

"[36] Jeffrey Bloomer of Slate favorably compared the film's "genre maturity", "amoral survivalism and malleable sense of good and evil", "brutal efficiency" and "weary humor" to John Carpenter's Assault on Precinct 13 and praised the cast, writing "If the world knows any justice[...] then the Screen Actors Guild will remember this cast when it doles out its awards next year".

[37] James Berardinelli concludes the film is "for anyone who enjoys sitting through 90 tense minutes and feeling the attendant adrenaline rush.

[6] Leslie Felperin of The Hollywood Reporter wrote that it's entertaining but "less disciplined, less original and less memorable work than Blue Ruin".
