The disparate pieces come together (this is magic to me) in an utterly believable and compelling portrayal. Reviews of the Proof: A Symposium play, including one that appeared in the Notices (October October 16, 2000 2000, pages 1082–1084), have been excellent. Buoyed by this New York University success, Proof moved to Broadway in October 2000.
