After gettting our first peak at the characters yesterday, today Disney serves up the first trailer for the film Saving Mr. Banks. “Before the movie could actually be made… Walt Disney had to get permission from Mary Poppins creator and children’s book author P.L. Travers. Saving Mr. Banks — due out in theaters this December — tells the story of that process and so much more. The cast includes the likes of Emma Thompson, Tom Hanks, Colin Farrell, Paul Giamatti, Jason Schwartzman, Bradley Whitford, Annie Rose Buckley, Ruth Wilson, B.J. Novak, Rachel Griffiths, Kathy Baker, and others.”
