EXCLUSIVE: Romy Rosemont and Mary Birdsong have been cast in Roseanne Barr’s NBC comedy pilot Downwardly Mobile. Co-created by Barr, her boyfriend John Argent and showrunner Eric Gilliland, the multicamera Downwardly Mobile stars Barr as Rose, the proprietor of a mobile home park and surrogate mother to the unique people who live there in a challenging economy. Birdsong, repped by UTA and manager Stacy Abrams, will play Kathie Lee, quintessential “trailer trash” who runs the pizza/beer joint in the park. Rosemont, repped by Domain and Main Title, will play Sheila, a resident of the mobile park who works as a nurse on the “death floor” at a nursing home. The pilot expands Rosemont’s relationship with 20th TV; she also recurs on the studio’s Fox musical dramedy Glee as Finn’s mother.
