UPDATE: She emailed me back. The play is Wittenberg "about a fictional meeting of Hamlet, Faustus, and Martin Luther at the University of Wittenberg" and she plays "all the female roles - Helen of Troy, Gaia, and more.." It's written by David Davalos, is part of PlayFest and runs January 21 - February 15, 2009. Here's the official description:
This sprightly and hilarious battle of wits features university colleagues Dr. Faustus (a man of appetites), versus Martin Luther (a man of faith), and their struggle for the soul of young Hamlet, Prince of Denmark (a youth struggling not only with his beliefs but also with his tennis game!). Come hear the story behind the story of Hamlet in a highly entertaining and humorous exploration of reason versus faith. Featuring Eric Hissom and Jim Helsinger.
