The Berwick Street Film Collective was formed in 1970, and produced a series of feature documentaries until around 1980. The work of the collective was based on the film making, both individual and collaborative, of its small group of members – Richard Mordaunt, Marc Karlin, Mary Kelly, and Humphry Trevelyan. Broadly speaking, these films were seen as being part of the avant garde of British documentary film in the 1970s.
