Lorenzo's Oil is a 1992 American drama film directed by George Miller. It is based on the true story of Augusto and Michaela Odone, two parents in a relentless search for a cure for their son Lorenzo's adrenoleukodystrophy (ALD). The film was nominated for two Academy Awards. It was filmed primarily from September 1991 to February 1992 in Pittsburgh, Pennsylvania. The film had a limited release in North America on December 30, 1992, with a nationwide release two weeks later on January 15, 1993.

Lorenzo’s oil is 4 parts of glyceryl trioleate and 1 part glyceryl trierucate, which are the triacylglycerol forms of oleic acid and erucic acid and are prepared from olive oil and rapeseed oil. It is used in the investigational treatment of asymptomatic patients with adrenoleukodystrophy (ALD). The oil was formulated by Augusto and Michaela Odone after their son Lorenzo was diagnosed with the disease in 1984, at the age of five, with the actual production initially developed by retired British scientist Don Suddaby (formerly of Croda International). Suddaby and his colleague, Keith Coupland, received U.S. Patent No. 5,331,009 for the oil. The royalties received by Augusto were paid to the Myelin Project which he and Michaela founded to further research treatments for ALD and similar disorders. The Odones and their invention obtained widespread publicity in 1992 because of the film Lorenzo’s Oil.
