A hit-Broadway play originally written by John Pielmeier will begin to dazzle thespians at Theatre Rocks! in Ennis this weekend.

Local actors and actresses, under the direction of Bill Rhoten, open “Agnes of God” for a four-week run beginning Friday night at Theatre Rocks!, located at 505 NW Main St. in Ennis.

Summoned to a convent, Dr. Martha Livingstone, a court-appointed psychiatrist (played by Samantha Jo Green), is charged with assessing the sanity of a novice nun (Cassidy Hortman). Livingstone’s questions force a re-examination of the meaning of faith and the power of love, leading to a dramatic, compelling climax.

The part of Mother Miriam Ruth is dual cast, with Sheryl Sullivan and Lisa Rosewell each portraying the role for five performances.

In a Theatre Rocks! promotional video, Sullivan explains her love for acting began in the second grade in a UIL contest for storytelling. Sullivan was encouraged by her mother because she was a "pretty good storyteller," she added with a laugh. "I've been telling stories ever since."

Sullivan said when she first heard Theatre Rocks! tabbed "Agnes of God" as its next production, she thought "there's a role in there for me."

"I used to think that about every show, but there are certain roles I just can't play anymore," she added. "This was a real meaty one. Much like one of my other really, really favorite roles in 'The Glass Menagerie.'"

Sullivan explained that she can "see some similarities" in the roles of Amanda Wingfield in "The Glass Menagerie" and Mother Miriam Ruth in “Agnes of God."

"Yes, she's hard and sometimes feels kind of mean, but I think she has a deep down love of God and creation," Sullivan said. "She sees everything through that lens."
