David Mamet's Glengarry Glen Ross is arguably, though not that arguably, the author's best-known, best-loved, and all-around best play. (Thanks to 1992's celebrated film version, I have friends - including friends who don't really like plays - who can quote entire scenes verbatim.) And it's no overstatement to say that the cast recruited for the Curtainbox Theatre Company's presentation of this exhilaratingly profane comedy is ridiculously gifted. At one point here, you'll find Michael Kennedy, Pat Flaherty, Eddie Staver III, Louis Hare, and Daniel D.P. Sheridan all sharing the Village Theatre stage, and that's before David Furness and Tristan Tapscott show up.
