Stephen Guarino has nabbed a key role in Showtime’s upcoming pilot I’m Dying Up Here.

The Happy Endings alum will play Sully, a zany stand-up out of Chicago who is described as “over-the-top to the point of tiresome” in the dark comedy. He joins the previously announced RJ Cyler (Me and Earl and the Dying Girl), who will portray Adam, a struggling comedian willing to do anything to make it.

Produced by Endemol Shine Studios and Assembly Entertainment, the hourlong project is written by Dave Flebotte (Will & Grace). Flebotte, Jim Carrey, Michael Aguilar (The Departed) and Christina Wayne (Copper) serve as executive producers. The pilot, which is scheduled to shoot this fall, will be directed by 50/50 and Warm Bodies helmer Jonathan Levine.

Guarino is repped by CAA and Haven Entertainment, along with attorneys Jon Moonves and Gordon Bobb at Del Shaw Moonves Tanaka Finkelstein & Lezcano.
