Joshua Oppenheimer is an movie director from the United States now based in Copenhagen, Denmark.

Oppenheimer's The Act of Killing centres on Indonesian death squad leaders who killed thousands of Communists in the 1960s, and was recently awarded a BAFTA. It was also nominated for the "best documentary" Oscar.

In addition to his cinematography, Oppenheimer is a senior researcher at the UK Arts and Humanities Research Council's Genocide and Genre project.

He spent more than a decade "with militias, death squads and their victims to explore the relationship between political violence and the public imagination", said the research council.
