Buñuel's My Last Breath is the most fun nonfiction book I've read. Coauthored by his friend and collaborator Jean-Claude Carrière, this must also be one of the best autobiographies ever.
Buñuel was a true surrealist. In this book he explores all his surrealist obsessions and themes of sex, death, dreams, memory, and anti-religiousness with irreverent humour. The book is full of life.
It's interesting to read his cinematic journey and his approach to his art. His account of his days in the surrealist movement is fascinating. It was a bunch of grown men playing pranks in public. You learn more about the politics between members of surrealist movement, the movement's dissolution, Salvador Dali's inflated ego, his excommunication from the movement, and his own encounters with the morbidities of human life.
