Based in Brighton and London, Dartmouth Films was founded in 2008 to concentrate on producing theatric documentaries which have an impact. One of its first films was The End of the Line, about the threat to the world’s oceans from overfishing. The film was the subject of an independent impact study which showed the film’s role on altering public attitudes, political policy and corporate behaviour. Since then Dartmouth has diversified to distribute films for other independent producers, as well as producing its own films. It produced and distributed the last four films of the journalist John Pilger; in 2022 it won the Screen International award for best documentary campaign and in 2023, in partnership with climate emergency activist groups, distributed Josh Appignanesi’s My Extinction. In 2024 it will release its next production – Lorna Tucker’s Someone’s Daughter, Someone’s Son, a film about homelessness and what can be done to end it. Dartmouth’s founder, Christopher Hird, is the author of Investigative Journalism Works: the mechanism of impact. Dartmouth welcome approaches from other filmmakers who want to work in partnership on production or distribution of documentaries.
