Tom Hanks and Emma Thompson in 'Saving Mr. Banks'Francois Duhamel/Disney

"Mary Poppins" has dazzled millions of moviegoers since its release in 1964, with its beautiful songs and heartfelt storyline. This December, audiences can get a closer look at the making of "Poppins" with Disney's "Saving Mr. Banks."

The drama takes you inside the film's creative process, as Walt Disney (played by Tom Hanks), desperately attempts to mount a production of the movie, while P.L. Travers (played by Emma Thompson), the notoriously protective author behind the original book, seeks to make sure her novel isn't ruined in the transition.
