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.
