Nightcleaners (Part 1) and ‘36 to ‘77 were made by a collective of independent artists and filmmakers working together, sharing time, equipment and expertise. The individuals involved in these documentaries have also gone on to make an extensive and varied body of work outside of the collective. The links below provide more information on each artist’s unique career.

Marc Karlin - https://spiritofmarckarlin.com/

Marc Karlin was a British filmmaker and a central member of the Berwick Street Film Collective, whose politically engaged, formally experimental documentaries helped define independent UK cinema from the 1970s onward. Through works such as Nightcleaners (1975), For Memory (1982), and his later Channel 4 essay films, he explored themes of memory, labour, and political consciousness with a philosophical and visually innovative approach. His films remain key contributions to the evolution of the essay documentary and the politics of representation in late-20th-century Britain.

Mary Kelly - https://www.marykellyartist.com/

Mary Kelly is an influential artist whose project-based work explores feminism, identity, and historical memory through large-scale narrative installations. After studying painting in Florence and teaching in Beirut, she moved to London in 1968, where her engagement with feminist theory shaped landmark works of the 1970s, including Post-Partum Document (1973–79), Women & Work (1975), and the film Nightcleaners as part of the Berwick Street Film Collective. Her subsequent projects—such as Interim, Gloria Patri, Mea Culpa, and Circa 1968—extend her examination of the body, war, trauma, and collective memory through experimental materials and forms. Kelly has exhibited widely, received major honors including a Guggenheim Fellowship, and held significant academic posts at UCLA and USC.

James Scott - http://www.james-scott.com/

James Scott studied painting and theatre design at the Slade School of Fine Art in the early 1960s, where his interest in film led to his acclaimed debut The Rocking Horse (1962) and, soon after, the chance to direct his first feature with Tony Richardson at age twenty-one. He went on to merge filmmaking with his art background through pioneering films on artists such as David Hockney and Richard Hamilton, later co-founding the Berwick Street Film Collective and creating the influential political documentary Nightcleaners. After further experiments with narrative form, he directed the Academy Award–winning A Shocking Accident (1982), adapted from a Graham Greene story. Having made more than twenty-five films, Scott moved to Los Angeles in the early 1990s and returned to painting, drawing, and printmaking, and he has recently completed a new artist film on the Catalan painter and activist Antoni Tàpies.
