LUIS BUÑUEL WAS ONE OF THE GREAT FILM-MAKERS OF THE TWENTIETH CENTURY. GWYNNE EDWARDS ANALYSES HIS WORK IN THE CONTEXT OF BUÑUEL'S PERSONAL OBSESSIONS - SEX, BOURGEOIS VALUES AND RELIGION. Luis Buñuel [1900-1983] was one of the truly great film-makers of the twentieth century. Shaped by a repressive Jesuit education and a bourgeois family background, he reacted against both, escaped to Paris, and was soon embraced by André Breton's official surrealist group. His early films are his most aggressive and shocking, the slicing of the eyeball in _Un Chien andalou _ [1929] one of the most memorable episodes in the history of cinema. _The Forgotten Ones_ [1950] and _He_ [1952], made in Mexico, were followed, from 1960, in Spain and France, by the films for which he is best known: _Viridiana_ [1961], _Belle de jour_ [1966], _Tristana_ [1970], _The Discreet Charm of the Bourgeoisie_ [1972], and _That Obscure Object of Desire_ [1977]. Gwynne Edwards analyses the films in the context of Buñuel's personal obsessions - sex, bourgeois values, and religion - suggesting that the film-maker experienced a degree of sexual inhibition surprising in a surrealist. GWYNNE EDWARDS is Professor of Spanish at the University of Wales, Aberystwyth.
