Tom Hanks is in talks to play Walt Disney in Saving Mr. Banks, a look at how Mary Poppins came to life on the big screen.

Emma Thompson is also in talks to join the film as children's author P.L. Travers, upon whose book Mary Poppins is based.

Kelly Marcel wrote the screenplay, which wound up on 2011's Black List. The story will mainly focus on P.L. Travers's life, and her apprehension at having her literary character brought to the big screen.
