What will the biggest movie at the box office be this weekend? It very well may be "Knight and Day," the new romcom-action send up of the action movie genre with megastars Tom Cruise and Cameron Diaz.

James Mangold, director of "Knight and Day," joins the program to talk about why his new action comedy isn't that different from his Oscar-winning film "Walk the Line," and how "Girl Interrupted" (another of his Oscar winners) and "3:10 to Yuma" have more in common than one might see at first glance.
