Glengarry Glen Ross is a 1992 American drama film, adapted by David Mamet from his acclaimed 1984 Pulitzer Prize- and Tony-winning play of the same name. The film depicts two days in the lives of four real estate salesmen and how they become desperate when the corporate office sends a representative to "motivate" them by announcing that, in one week, all except the top two salesmen will be fired. The film, like the play, is notorious for its use of profanity, leading the cast to jokingly refer to the film as "Death of a Fuckin' Salesman". The actual title of the film comes from the names of two of the real estate developments being peddled by the salesmen characters (Glengarry Highlands and Glen Ross Farms).

Glengarry Glen Ross had its world premiere at the Venice Film Festival where Jack Lemmon won the Volpi Cup for Best Actor. The film was not a commercial success, making only $10.7 million in North America, just below its $12.5 million budget. It was critically well-received with highly positive reviews by most of the major critics. Al Pacino was nominated for an Academy Award and a Golden Globe for Best Supporting Actor for his work in the film.
