The fiercely original film-maker, poet and artist Jeff Keen, who has died aged 88, defied categorisation. He produced a vast body of paintings, drawings, sculpture and punchy Beat poetry, but is best known for his films, which incorporated collage, animation, found footage and live action -- often all in one work. Keen used highly innovative techniques of superimposition and editing, and frequently etched and degraded the film surface. Works such as Marvo Movie (1967), Rayday Film (1968-75) and Mad Love (1972-78) were shot with his friends and family either at home, on the streets of Brighton or at the local tip; their fantastical, DIY countercultural qualities evoked the spirit of Andy Warhol's Factory and the early cinema pioneers of Brighton, where Keen lived. Despite making his first film in his late 30s, he completed more than 70 films and videos throughout his life.
