Geoffrey Gilyard Unsworth, OBE, BSC (26 May 1914 – 28 October 1978) was a British cinematographer who worked on nearly ninety feature films during a career that wound up spanning over more than forty years.
He is best known for his work on critically acclaimed releases such as Stanley Kubrick's 2001: A Space Odyssey, Bob Fosse's Cabaret and Richard Donner's Superman.
The British news agency The Guardian has highlighted the nature of his work for Kubrick, in the words of fellow cinematographer Peter Suschitzky, given that Unsworth's approach reportedly "became the benchmark" for a given cinematic style.
He was responsible for integrating the work of a who's-who of cinematographers and visual effects designers (including Zoran Perisic, an animation stand crew member from 2001, who extended Kubrick's front projection technique for Superman), with the plausibility and sense of grandeur befitting a (mostly) reverent take on a superhero.
Unsworth's other work in the 1970s included the Oliver Cromwell biopic Cromwell in 1970, the 1972 John Barry musical Alice's Adventures in Wonderland, John Boorman's 1974 fantasy film Zardoz, The Return of the Pink Panther (the fourth film in Blake Edwards' Pink Panther series), Richard Attenborough's 1977 war epic A Bridge Too Far.
