Tom Hanks Plays Walt Disney In Preview Trailer [VIDEO]: Emma Thompson Portrays P.L. Travers In 'Saving Mr. Banks'

Tom Hanks plays Walt Disney in the movie "Saving Mr. Banks," which will be a biographical film about the production of the popular 1964 movie, "Mary Poppins." It is set for a December 2013 release in theaters.

Playing the role of author P.L. Travers will be another Academy Award winner in Emma Thompson. Travers wrote "Mary Poppins" and Tom Hanks plays Walt Disney as the two attempt to produce a movie version of the book.

The movie takes place in 1907 with Travers childhood in the 1960s. While they are filming the movie in California, she has flashbacks of her life as a child, according to Internet Movie Database (IMDB).

"Mary Poppins," which was released in 1964, would become one of Disney's signature and biggest hits, ranked among the top 25 money-making movies of all-time when adjusted for ticket price inflation over the years, according to BoxOfficeMojo.com.

Tom Hanks plays Walt Disney in the film, which is a role that hasn't been played in a movie with this production ever. The film, "Saving Mr. Banks," is being distributed by Walt Disney Pictures, which is a legacy that Walt Disney himself left behind after he died of lung cancer in 1966 at 65-years-old. P.L. Travers died at the age of 96 in 1996.

This upcoming film is partially based off the 1999 book "Out of Sky She Came" by Valarie Lawson.

Disney was particularly noted as a film producer and a popular showman, as well as an innovator in animation and theme park design. Disney World and Disney Land are two of the most famous theme parks in the world. He and his staff created some of the world's most well-known fictional characters including Mickey Mouse, for whom Disney himself provided the original voice.
