The Treasure of the Sierra Madre is a 1948 American Western adventure drama film written and directed by John Huston. It is an adaptation of B. Traven's 1927 novel of the same name, set in the 1920s. Two downtrodden men, played by Humphrey Bogart and Tim Holt, join forces with a grizzled old prospector, played by Walter Huston, the director's father, in searching for gold in Mexico. The Treasure of the Sierra Madre was one of the first Hollywood productions to be shot on location outside the United States (in the state of Durango with street scenes in Tampico, Mexico), although many scenes were filmed back in the studio and elsewhere in the U.S. In 1990, the film was selected for preservation in the United States National Film Registry by the Library of Congress as being "culturally, historically, or aesthetically significant".[3]
