[3] In addition to his photography, he has directed more than 30 films on six continents, often on controversial political and social themes, several of which have won major awards, including an International Emmy (for Damned in the USA - Berwick Universal Pictures, 1990),[4] awards from the Royal Television Society,[n 1] an Edward Morrow Prize,[n 2] and an Amnesty International Prize.

This was the first of half a dozen documentaries Yule made in Peru over the next two decades, and the start of an award-winning collaboration with the producer Andy Harries.

He has collaborated with several writers, including with Nicholas Shakespeare on films about Mario Vargas Llosa (1990) and Bruce Chatwin (1999); with Peter Oborne on exposés of Robert Mugabe (2003) and the conspiracy surrounding the cricketer Basil D'Oliveira (2004); as well as with Darcus Howe, Miranda Sawyer, Paul Morley, Luke Holland and others.

Producers with whom he has collaborated include Jonathan Stack, George Carey, Roy Ackerman, Samir Shah and Markus Davies.

In 2008 Yule completed a three-film 60-year history of apartheid in South Africa and its consequences (White Lies, 1994 - about the International Defence and Aid Fund;[10] The Basil D'Oliveira Conspiracy, 2004; and The Captain and the Bookmaker, 2008[11]– the latter two of which focus on the political history of South Africa as seen through the prism of cricket, including the downfall of Hansie Cronje).

While there he originated "The Big Picture", an intensive, hands-on documentary film production course aimed at training a new generation of filmmakers and technicians to make fresh, socially relevant, local programming.
