Having cut his teeth on the investigative documentary strand World in Action, known for its forceful and unorthodox journalistic approach, Paul Greengrass has become one of the world's most popular filmmakers. His films, which often explore real-world anxieties and confront both social and political issues, include 22 July, three of the Jason Bourne franchise, Captain Phillips, United 93 and Bloody Sunday. In conversation with journalist and broadcaster Danny Leigh at Doc/Fest 2019, Paul discusses his journey from TV documentaries in the UK to feature films in Hollywood, the evolution of his signature vérité-style, and his thoughts on the need to open up the film industry to less privileged and working class talent to ensure future creative diversity.
