New Sitcom 'Mulaney'

Mulaney is a multi-camera comedy show about John Mulaney, a struggling stand-up comic who is trying to “be a good person.” He finds help in his journey from his boss Lou, played by Martin Short, and his gay neighbor, Oscar, played by Elliott Gould. John will also be struggling with his roommates, Seymour (Griffin Newman) and Jane (SNL’s Nasim Pedrad).
