Written by Christopher Durang and directed by Marshall Brickman (The Manhattan Project), this all-star cast features Diane Keaton as Sister Mary, and Brian Benben, Wallace Langham and Laura San Giacomo as the former students whose lives were forever scarred by the teachings of the dogmatic nun. A confrontation between students and teacher is the central event of a Christmas lecture given by Sister Mary, when her former students co-opt the classic pageant and turn the Sister's original teachings on their head. The revisionist portrayal of the biblical story highlights her students' disillusionment and disappointment. Their lifestyle choices provoke Sister Mary's intolerance and anger, resulting in an eruption of violence. Executive produced by Kirk Stambler and Victoria Tennant. Newly remastered.

Diane Keaton stars in this adaptation of Christopher Durang's popular one-act play Sister Mary Ignatius Explains It All for You as Sister Mary, a nun who teaches at a parochial school and has very firmly held ideas about sin, forgiveness, and the importance of church doctrine. As Sister Mary delivers a lecture on sin and its consequences, she's interrupted by several of her former students, who have little positive to say about how a Catholic education has impacted their lives. SISTER MARY EXPLAINS IT ALL also stars Brian Benben, Jennifer Tilly, and Wallace Langham; it was produced for the Showtime premium cable network, where it first aired in May 2001.
