Waitress, according to press notes, concerns "Jenna, a waitress and expert pie maker, [who] is stuck in a small town and a loveless marriage. When a baking contest in a nearby county offers her a chance at escape, Jenna must weigh her commitments against a rare shot at freedom and recognition. Her customers, co-workers, and the town’s handsome new doctor all offer her conflicting recipes for happiness — but Jenna must ultimately decide for herself."
ART posted a sizzle video from the production. It features Mueller, Settle, and other cast members, plus director Diane Paulus, at rehearsals.
Titled "Waitress: A First Look," the video is currently available only on Facebook.
