Glengarry Glen Ross is a 1992 American drama film adapted by David Mamet from his 1984 Pulitzer Prize–winning play Glengarry Glen Ross, and directed by James Foley. The film depicts two days in the lives of four real estate salesmen, and their increasing desperation when the corporate office sends a motivational trainer to threaten them that all but the top two salesmen will be fired within two weeks. The setting is never explicitly stated. The play is set in Mamet’s hometown Chicago, Illinois, but the film includes numerous references to New York City, including an establishing shot of a New York City Subway platform followed by a close-up shot of a New York Telephone-branded payphone, NYPD police cars and insignia, New York license plates, and mostly New York accents. Film critics and journalists have nonetheless placed the setting in Chicago, possibly based on their familiarity with the original play. In addition, several Chicago suburbs are mentioned at various times (Morton Grove, Batavia, Kenilworth). Exterior shots were filmed on location in Sheepshead Bay, Brooklyn.
