For a play that famously starts arguments -- about sexual harassment, political correctness and the irreconcilable differences between men and women -- one thing is indisputable about David Mamet's Oleanna: It's a drama of the highest order. TIME magazine named it one of its "Ten Best Plays," and Roger Ebert called Oleanna "one of the most stimulating experiences I've had in a theater." In this charged two-character drama, a professor and his female student become embroiled in a war of words. Things take a dangerous turn when perceptions differ, and she later accuses him of sexual exploitation. As the serene campus transforms into an explosive battleground, Mamet -- the Pulitzer-winning writer of Glengarry Glen Ross -- begs you to question what it means to be right or wrong. Haley Johnson directs this seething investigation of "political correctness," featuring Candace Joice and Stephen Krusoe and produced by Progressive Theatre Company, at Denver's John Hand Theater.
