'Old Christine's' Tricia O'Kelley joins Roseanne Barr pilot at NBC

tricia-okelley-roseanne-pilot.jpgTV's pilot season is starting to wind down, but a few final pieces of casting are taking place, including a changeup in Roseanne Barr's NBC comedy and CBS finding the the final lead for its comedy "Super Fun Night."

- Tricia O'Kelley, who played mean mom Marly Eckhardt on "The New Adventures of Old Christine," has joined the cast of "Downwardly Mobile," Barr's comedy pilot set at mobile home park. She replaces Salli Richardson ("Eureka"), who according to Deadline "could not sync up" with the other actors when the pilot had a run-through last week.

O'Kelley's character, Mrs. Denby, is the wife of a hedge-fund manager who has just lost all his money and hates being in the mobile park. She will clash with Barr's character, Rose, who manages the park. O'Kelley's credits also include recurring parts on "Secret Life of the American Teenager" and "Gilmore Girls."

Other casting news, also from Deadline:

- "Super Fun Night," a comedy about three friends who decide to step up their weekend fun, has cast Groundlings member Edi Patterson as its third lead opposite "Bridesmaids" actress Rebel Wilson (who also wrote the pilot) and Jenny Slate ("Saturday Night Live"). Patteron's on-screen credits include "The Underground" and episodes of "CSI" and "Weeds."

- Zachary Gordon, the title character in the "Diary of a Wimpy Kid" movies, will play one of Mary McCormack's kids in an ABC comedy pilot from "Old Christine" creator Kari Lizer. "In Plain Sight" star McCormack will play a recently fired executive who tries to be a full-time mother to her two children for the first time. Gordon replaces Aidan Potter ("The Middle"), who was let go after producers decided to make the character a few years older.
