Green Room is a 2015 American horror-thriller film 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. The film came from Saulnier's desire to direct a thriller set in a green room.

Principal photography took place during October 2014 in Portland, Oregon. The film was financed and produced by Broad Green Pictures. Green Room was screened in the Directors' Fortnight section at the 2015 Cannes Film Festival. At the 2015 Toronto International Film Festival, the film finished third in the balloting for the Grolsch People's Choice Midnight Madness Award. The film began a limited release on April 15, 2016, before being widely released on May 13 through A24. It appeared on many critics' lists as one of the best films of 2016 and received a 2017 Empire Award nomination for Best Horror, but grossed just $3 million against a budget of $5 million.
