Scoop: 24's Mary Lynn Rajskub Joins ABC's Megan Hilty Comedy Pilot as... Greg Grunberg's Twin?

Californication Cast Mary Lynn Rajskub

24 vet Mary Lynn Rajskub has joined the cast of ABC’s Untitled Judah Miller Project in a series-regular role, TVLine has confirmed.

The single-camera project centers on a Tony Award-winning mother (Smash‘s Megan Hilty) and a risk-averse, cerebral father (Heroes‘ Greg Grunberg) who are blessed with a son who is a natural-born competitive athlete. They are forced outside their parental comfort zones and into the high-octane world of youth sports.

Rajskub will play Susie, the self-serving and opportunistic twin sister of Grunberg’s Gary.

The cast also includes Marissa Jaret Winokur (AKA Miller’s real-life wife) as Hilty’s soccer-mom foil.

Miller, whose credits include American Dad! and King of the Hill, penned the script and will serve as an EP.
