The prim and proper Mary Poppins author P.L. Travers (Emma Thompson) meets the exceedingly informal Walt Disney (Tom Hanks) in the first clip from Disney's Saving Mr. Banks. John Lee Hancock directs this drama that follows Mary Poppins' arduous journey to the big screen, with P.L. Travers fighting major changes to her book all the way. In addition, we have a behind-the-scenes featurette with John Lee Hancock and Emma Thompson discussing the intricacies of playing P.L. Travers, along with more footage from the December 13 release.
