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 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 developments mentioned in the play. Glengarry Highlands is the prime real estate everyone is attempting to sell now; Glen Ross Farms 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 21 September 1983, where Bill Bryden's production in the Cottesloe Theatre was acclaimed as a triumph of ensemble acting.The play opened on Broadway on 25 March 1984, at the John Golden Theatre, and closed on 17 February 1985 after 378 performances. 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. It 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. A film adaptation was released in 1992, with James Foley directing and Mamet providing the screenplay. The cast featured Al Pacino, Jack Lemmon, Alec Baldwin, Ed Harris, Alan Arkin, Kevin Spacey and Jonathan Pryce. Source: Wikipedia (en)
