Glengarry Glen Ross

This is the actual filming location of the office scenes in Glengarry Glen Ross, a 1992 American drama, adapted by David Mamet from his 1984 Pulitzer Prize- and Tony-winning play of the same name, and directed by James Foley. The film depicts two days in the lives of four real estate salesmen and how they become desperate when the corporate office sends a trainer 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 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.
