Why She Might Work: She's been channeling the Mia Farrow look for years now (remember when Williams had long hair? Neither do we), and we know from "Brokeback Mountain" and even "My Week with Marilyn" she's able to convey an open quality as well as a growing sense of anxiety, no sweat.
Why It's a Bad Idea: There's absolutely no way an Oscar nominee is taking on an NBC miniseries. Period.
