The Good Wife has a knack for casting perfect guest-stars — Martha Plimpton, Michael J. Fox, Matthew Perry, Anika Noni Rose, Carrie Preston. Now we can add Stockard Channing to the list. She's been cast as Alicia's mother, EW reports, and she'll appear in at least one episode this season. Mamas, don't let your babies grow up to be lawyers who tolerate infidelity and don't stand up for themselves enough even though they always have perfect skirt suits.
