Greenhalgh's film writing debut was a biopic of Joy Division frontman Ian Curtis, the 2007 film "Control", which was directed by Anton Corbijn. He was awarded the Carl Foreman BAFTA award at the 61st British Academy Film Awards, and was nominated for Best Screenplay at the British Independent Film Award for his work on the film. "Control" was adapted from the book, "Touching From a Distance," written by Ian Curtis' wife, Deborah Curtis.
