Popcorn With Peter Travers

Michelle Dockery's "Good Behavior" may indirectly be filling a void for her fans still clinging on to the days of "Downton Abbey." To be clear, Dockery's role in the new TNT drama is not at all similar to her former character, the lovely Lady Mary Crawley. But for many, that's what makes it so special. Dockery recently stopped by ABC's "Popcorn With Peter Travers" to talk about her new role as Letty Raines, a woman with a shady past who's fresh out of jail. And she drops new details about that "Downton Abbey" movie that fans have been begging to see. * ABOUT POPCORN WITH PETER TRAVERS: This show features the world's biggest stars and top moviemakers.
