Keep the Lights On is an American drama film, which premiered at the 2012 Sundance Film Festival and was released in New York City and Los Angeles on September 7, 2012 by Music Box Films. Directed by Ira Sachs, and written by Sachs and Mauricio Zacharias, the film stars Thure Lindhardt as Erik, a Danish filmmaker living in New York City to work on a documentary film about artist Avery Willard; while there, he enters into a loving but complicated long-term relationship with Paul (Zachary Booth), a lawyer in the publishing industry who struggles with drug addiction. The film's cast also includes David Anzuelo, Maria Dizzia, Julianne Nicholson, Souléymane Sy Savané, Miguel Del Toro and Paprika Steen.
The film is based on Sachs' own past relationship with Bill Clegg, a literary agent who published his own memoir about his struggles with addiction, Portrait of an Addict as a Young Man, in 2010.
