Glengarry Glen Ross follows the cutthroat world of real estate where salesmen are vying for the best leads to make the biggest sales. The play was produced on Broadway in 1984 under the direction of Gregory Mosher following London and Chicago runs. The drama earned playwright Mamet the Pulitzer Prize and Best Play Tony Award nomination that year and was later adapted by the scribe for the 1992 film.

The design team of Glengarry Glen Ross will feature Santo Loquasto (sets), Laura Bauer (costumes) and Kenneth Posner (lighting). Jeffrey Richards, Jerry Frankel and JAM Theatricals produce the work with Philip Lacerte, Boyett/Haber, Ronald Frankel, Zen Dog Productions, Barry Weissbord, BG Partners, Boyett Ostar Productions in association with Swinsky/Berger and by special arrangement with Roundabout Theatre Company.

Mamet will also see his new play Romance staged Off-Broadway at the Atlantic Theatre Company — which he co-founded with actor William H. Macy. Mamet has also penned Speed the-Plow, American Buffalo, Oleanna, Cryptogram, The Old Neighborhood, Boston Marriage and Sexual Perversity in Chicago. His screenplays include "State and Main," "The Spanish Prisoner" and "Heist."
