Exclusive: Grey's Recruits Two Carnivale Grads!

Amy Madigan has booked a multi-episode arc on Grey's Anatomy, sources confirm to me exclusively. The Oscar-nominated thesp — and former co-star of HBO's gone-but-not-forgotten Carnivale — is playing a psychiatrist who, and I'm just speculating here, may be the one to help Meredith get over her commitment issues, thus paving the way for the Mer/Der reunion Shonda Rhimes has been hyping.Meanwhile, Madigan's former Carnivale co-star, Clea DuVall, will fill the "everywoman housewife" role I teased in last week's Ask Ausiello. Her George Clooney-esque husband will be played by Jason O'Mara (Men in Trees, In Justice). I'm guessing one of them will be a patient. Both are on board for two episodes.Oh, Carnivale, how I miss thee….
