“The proper route to understanding the world is to examine our mistakes about it.” Errol Morris is an American documentary filmmaker and writer, known for his innovative style and investigative approach to nonfiction cinema. He graduated in history from the University of Wisconsin–Madison and pursued graduate studies in philosophy at Princeton and Berkeley, though he did not complete his Ph.D. Morris began his filmmaking career with Gates of Heaven (1978), a meditation on pet cemeteries that impressed directors such as Werner Herzog. He gained wide recognition with The Thin Blue Line (1988), a documentary that contributed to the release of a man wrongly convicted of murder. Other notable works include Standard Operating Procedure (2008), about the Abu Ghraib scandal, and Wormwood (2017), a hybrid series blending documentary and fiction that examines a secret CIA program. His technique is marked by the use of the Interrotron, a device that allows interviewees to look directly into the camera while speaking, creating a feeling of direct connection with the viewer. In 2003, he won the Academy Award for Best Documentary Feature for The Fog of War, a portrait of former Secretary of Defense Robert S. McNamara. In addition to his work as a filmmaker, he has written articles on legal, scientific, and philosophical topics, contributing to outlets such as The New York Times and The New Yorker. His reflective, inquisitive, and often ironic style has made him a key figure in the evolution of contemporary documentary filmmaking.
