Sister Mary Explains It All

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.
