This sounds like a promising new project: John Corbett as Toni Collette's leading man in the Showtime comedy pilot United States of Tara. The show comes from the pen of Diablo Cody, fresh off her Oscar win as the screenwriter of Juno, and the pilot's director is Craig Gillespie who received plaudits for the indie hit Lars and the Real Girl. Oh, and did I mention that Steven Spielberg is one of the producers? Considering this collection of talent and Showtime's recent programming successes, United States of Tara sounds like another ace for the cable net.
