Glengarry Glen Ross is a play by David Mamet that won the Pulitzer Prize in 1984. The play shows parts of two days in the lives of four desperate Chicago real estate agents who are prepared to engage in any number of unethical, illegal acts—from lies and flattery to bribery, threats, intimidation and burglary—to sell undesirable real estate to unwitting prospective buyers. It is based on Mamet's experience having previously worked in a similar office.
The title comes from two real estate properties mentioned in the play: Glengarry Highlands, which is currently the prime real estate everyone is attempting to sell, and Glen Ross Farms, which is mentioned by several characters as having been very lucrative for those selling it several years ago.
The world premiere was at the National Theatre in London on September 21, 1983 where Bill Bryden's production in the Cottesloe Theatre was acclaimed as a triumph of ensemble acting.
The play opened on Broadway on March 25, 1984 and closed on February 17, 1985. The production was directed by Gregory Mosher and starred Joe Mantegna, Mike Nussbaum, Robert Prosky, Lane Smith, James Tolkan, Jack Wallace and J. T. Walsh. The production was nominated for four Tony awards including Best Play, Best Director, and two Best Featured Actor nominations for Robert Prosky and Joe Mantegna, who won the production's one Tony.
