Written by Martin Casella — whom you may or may not know as the playwright of such theatrical gems as Paydirt, The Big Enchilada, and George Bush Goes to Hell — The Irish Curse deals with the stereotype that many an Irishman is cursed with a small penis (often accompanied by large testicles — “all potatoes, no meat” — and a boozy red schnoz — “red nose, short hose”). Set in New York in the basement of a Catholic church, Casella’s thought-provoking, character-driven comedy focuses on a support group for the poorly endowed, where measuring up is no small issue. Directed by Roberto Prestigiacomo, AtticRep’s production of The Irish Curse stars Rusty Thurman, Lawrence Coop, Tyler Keyes, Rick Frederick, and Rodman Bolek.
