GirlsJake Lacy has joined the ensemble cast of Showtime’s new hourlong comedy series I’m Dying Up Here as a series regular.

I’m Dying Up Here, executive produced by Jim Carrey, follows up and coming comedians in LA in the 1970s, who are mentored by “Goldie” (Melissa Leo), a brassy comedy club owner who rules over her business with an iron fist and nurtures her comedians with tough love. Ari Graynor, Andrew Santino, RJ Cyler, Al Madrigal, Erik Griffin and Stephen Guarino star as the main stand-ups at the club. Michael Angarano and Clark Duke play ballsy young comedians from Boston who move to L.A. with the hopes of making it big. Alfred Molina, Sebastian Stan, Robert Forster, Jon Daly, Dylan Baker, Brianne Howey, Ginger Gonzaga and Cathy Moriarty guest star.

Lacy will play a stand-up comic who gained some notoriety a few years back by blowing off The Tonight Show Starring Johnny Carson on the night he was scheduled to appear. His issues with substance abuse and family tragedy inform his comedy as he tries to re-acclimate into the early ‘70s L.A. comedy scene. Though not everyone is quick to welcome him back, nor is he interested in conforming to their idea of what comedy is.

Lacy was recently seen opposite Rooney Mara and Cate Blanchett in Oscar-nominated Carol. His additional film credits include How To Be Single, Obvious Child, Intramural and Love, The Coopers. His upcoming films include Their Finest Hour and a Half and John Madden’s Miss Sloane. On the TV side, he’s best know for his roles in Girls, Better With You, and The Office.

I’m Dying Up Here was written Dave Flebotte (Masters of Sex, Will & Grace) based on the non-fiction book of the same name by William Knoedelseder. Flebotte executive produces with Carrey, Michael Aguilar and Christina Wayne for Endemol Shine Studios and Assembly Entertainment. The pilot was directed by Jonathan Levine. The series will shoot in L.A. this fall.
