Birdsong (Hairspray, Martin Short: Fame Becomes Me) and Romy Rosemont ("Glee") have been cast in Roseanne Barr's NBC comedy pilot "Downwardly Mobile." Co-created by Barr, John Argent and Eric Gilliland, the comedy stars Barr as Rose, the proprietor of a mobile-home park. Birdsong will play Kathie Lee, who runs the pizza joint in the park, and Rosemont ("Glee") will play Sheila, a resident of the mobile park.

Tony winner Martin (My Favorite Year) will join Judd Hirsch (Conversations With My Father, I'm Not Rappaport) and Ben Falcone in the CBS untitled pilot written by Falcone and Larry Dorf. The comedy centers on David (Falcone), a single 37-year-old who loses everything he has in the real-estate collapse and finds himself back at his parents' house. Hirsch and Martin will play David's parents. Falcone, Melissa McCarthy and Shana Goldberg-Meehan are executive producers.

Russell (Off-Broadway's Fat Pig) has signed on to star in FX's period drama pilot "The Americans." Created by Joe Weisberg and directed by Gavin O'Connor, the project centers on two KGB spies posing as Americans in suburban Washington, DC in the early 1980s. Weisberg, Graham Yost, Darryl Frank and Justin Falvey are executive producers.

As previously reported, Tony Award winner Norbert Leo Butz, Tony nominee David Harbour, Elizabeth Perkins, Jamie-Lynn Sigler, Julia Stiles, Sara Rue and Jeff Goldblum are among the other stage actors who will be seen in television pilots this season.
