The British Film Industry in 25 Careers tells the history of the British film industry from an unusual perspective - that of various mavericks, visionaries and outsiders who, often against considerable odds, have become successful producers, distributors, writers, directors, editors, props masters, publicists, special effects technicians, talent scouts, stars and, sometimes, even moguls. Some, such as Richard Attenborough and David Puttnam, are well-known names. Others, such as the screenwriter and editor Alma Reville, also known as Mrs Alfred Hitchcock; Constance Smith, the ''lost star'' of British cinema, or the producer Betty Box and her director sister Muriel, are far less well known. What they all have in common, though, is that they found their own pathways into the British film business, overcoming barriers of nationality, race, class and gender to do so.

Counterpointing the essays on historical figures are interviews with contemporaries including the director Amma Asante, the writer and filmmaker Julian Fellowes, artist and director Isaac Julien, novelist and screenwriter Hanif Kureishi, and media entrepreneur Efe Cakarel, founder of the online film platform MUBI, who''ve come into today''s industry, adjusting to an era in which production and releasing models are changing – and in which films are distributed digitally as well as theatrically.
