Who's doing what for whom this pilot season (per Variety and the Reporter): Emmy winner Christina Applegate, long wooed to return to network TV, has opted to star as an amnesiac woman in the ABC comedy Sam I Am. Jean Smart is Sam's mom, and Tim Russ (Star Trek: Voyager) is also in the cast. As first scooped by the Ausiello Report, Judging Amy Brenneman and Merrin Dungey (Alias) have come on board the Grey's Anatomy spin-off, playing Violet and Naomi. Melanie Griffith will guest on the pilot for the CBS musical drama Viva Laughlin. A conniving sexpot, Griffith's character could go recurring. Drew Carey's Diedrich Bader is the loyal friend of CBS' Skip Tracer. Jamey Sheridan (Law & Order: CI) is a wife-beater turned zombie in CBS' Babylon Fields. Stephanie Childers (Studio 60) is the mother of ABC's American Family. Ty Burrell (Out of Practice, indeed) is an ace reporter for Fox's Action News.
