Control is a 2007 British biographical film about the life of Ian Curtis, singer of the late-1970s English post-punk band Joy Division. It is the first feature film directed by Anton Corbijn, who had worked with Joy Division as a photographer. The screenplay by Matt Greenhalgh, was based on the biography Touching from a Distance by Curtis's widow Deborah, who served as a co-producer on the film. Tony Wilson, who released Joy Division's records through his Factory Records label, also served as a co-producer. Curtis' bandmates Bernard Sumner, Peter Hook, and Stephen Morris provided incidental music for the soundtrack via their post-Joy Division incarnation New Order. Control was filmed partly on location in Nottingham, Manchester, and Macclesfield, including areas where Curtis lived, and was shot in colour and then printed to black-and-white. Its title comes from the Joy Division song "She's Lost Control", and alludes to the fact that much of the plot deals with the notion that Curtis tried to remain in control of his own life, and yet had no control over his epilepsy and pharmaceutical side effects.
