The Big Screen: Thin Line Preview

The Big Screen looks in-depth at the most interesting new release in theaters each week. We also have a weekly conversation with a major movie star or mover-and-shaker in the North Texas film scene and we highlight movies and DVDs to watch this weekend. The Big Screen is hosted by Chris Vognar, movie critic for The Dallas Morning News (dallasnews.com) and Stephen Becker, reporter for Art and Seek, from KERA (artandseek.org).
