The story of Bern Tost and his career as a porn-movie auteur is as colourful and strange as any in the history of pornography. When the subject came of age, the world was still in the grip of post-war austerity. Tost's extraordinary outlook was to influence the sexual revolution of the 1960s; he was one of the few people to make sense of his era's cultural and moral chaos. Bruno Phillips' reflective biography is the most fascinating expose of the early porn industry and its players since Boogie Nights.
