“We’re overjoyed to have Sara Bareilles play Mary Magdalene, and I can guarantee that her interpretation of the standard ‘I Don’t Know How to Love Him’ will become an instant classic,” NBC Entertainment chairman Robert Greenblatt said Saturday ina statement. “I was lucky enough to see Sara in Waitress and she gave as moving and as beautifully sung a performance as I’ve seen on a Broadway stage in a long time.”

“To say I’m excited about this performance is the understatement of the century," said Bareilles. "This score and this musical have been a part of my life from a very young age and it will be one of the great thrills of my life to sing these iconic songs. It’s incredible to see the beloved medium of musical theatre being embraced by television audiences, and this cast and creative team is extraordinary. I feel extremely lucky to be a part of the project!”
