The "one-nun show" is written by Donovan with Marc Silvia, and is directed by Silvia.

The Laguna Playhouse previously staged three of the shows in the Late Nite Catechism series: Late Nite Catechism, Late Nite Catechism 2 and Sister's Christmas Catechism. Donovan portrayed Sister in all three productions.

'Til Death Do Us Part: Late Nite Catechism 3 is billed this way: "After teaching countless students all about the saints, venial sins, guilt, limbo, and more, Sister is now offering up her hilarious lessons on the Sacraments of Marriage and Last Rites, including her own wacky version of 'The Newlywed Game.' Classroom participation is a must, so bring along your sweetie and your sense of humor for some quality time with Sister, the feistiest new couples counselor in town. As always, each performance is unique and will appeal to people of all ages and faiths."

Donovan said in production notes, "Every performance is different, but that's what makes it more interesting and more exciting — you never know what you're going to get. By talking to people during the show, I get to know who is who, who we should pick on and who to leave alone. It's a skill you develop over the years of doing interactive theatre."

Opening night is April 4. For information and tickets, call (949) 497-ARTS (2787) or visit www.LagunaPlayhouse.com. The Moulton Theatre is at 606 Laguna Canyon Road, Laguna Beach, CA.
