Michael C. Hall ("Dexter," Hedwig and The Angry Inch), Martha Plimpton ("The Good Wife," PoA's Gun Show), and actor-playwright Hamish Linklater (The Big Short, "Legion") star in NUDITY RIDER, a world-premiere comedy by Linklater.   The cameras are ready to roll on the set of a New Orleans basic cable show, but the high-strung leading man, Keith Saturday, has a problem: his most up-close-and-personal scene has been unexpectedly rescheduled for today. And he's been eating. A lot. Now, an incisive production assistant (Hall) and no-nonsense makeup artist (Plimpton) must battle the clock - and assuage Saturday's ego - to save the shoot. After the episode, host Claudia Catania joins the cast and director Moritz von Stuelpnagel (Broadway's Hand to God, Bernhardt/Hamlet) for an in-studio interview about writing for radio and what it takes to be a successful actor.   NUDITY RIDER is presented with the support of Fred Wistow.
