Moritz Borman, the producer of Oscar-nominated films such as “The Quiet American” and “Under the Volcano” as well a frequent collaborator of Oliver Stone, died Wednesday in Munich, Germany. He was 71.

Borman’s death was confirmed by his longtime producing partners Eric Kopeloff and Philip Schulz-Deyle. A cause of death was not given.

The German-born Borman produced more than 25 feature films over the course of his career, ranging from political thrillers to literary adaptations to action blockbusters. Borman got his break working with director John Huston on 1984’s “Under the Volcano,” an adaptation of Malcolm Lowry’s acclaimed novel about an alcoholic British diplomat who is mourning his dead wife. It drew rave reviews and earned an Oscar nomination for Albert Finney’s lead performance as well as for its score. He would also produce “The Quiet American,” a 2002 film version of a Graham Greene novel about a love triangle that develops between a British journalist, an American spy and a young Vietnamese woman at the end of the First Indochina War. It earned a best actor Oscar nomination for Michael Caine and co-starred Brendan Fraser.

With Stone, Borman produced the historical epic “Alexander,” the 9/11 drama “World Trade Center,” the drug cartel thriller “Savages,” the George W. Bush biopic “W.,” and “Snowden,” a look at CIA whistleblower Edward Snowden.
