The first thing Jennifer Grey did when she received the script for Gwen Shamblin: Starving for Salvation — Lifetime's upcoming movie about the founder of the Weigh Down Workshop and controversial leader of Remnant Fellowship Church — was hit the internet.

"I knew nothing at all," says Grey of Shamblin. "I Googled her, and I got the visual right between the eyes." That visual — of Shamblin's gaunt, heavily made-up face and towering beehive of bleach-blonde hair — caught the actress by surprise. "I was completely riveted. I thought, 'Why me?'" she recalls with a laugh.
