It was Fluxus founder George Maciunas who introduced Yoko Ono to film. One day in 1966, he invited her to use his newly acquired high-speed camera and she made Film No.1 (MATCH). She explored her interest in the human body through works such as Bottoms (1966) and Fly (1970). She also facilitated the creation of one of the most jaw-dropping films of the 1970s: after seeing Alejandro Jodorowsky’s psychedelic Western El Topo, Ono and Lennon financed his third feature, the hallucinatory spiritual quest The Holy Mountain (1971).
