Tom Hanks Transforms Into Walt Disney in 'Saving Mr. Banks'

Disney has broken the seal on the first movie trailer for Saving Mr. Banks, which tells the story of how Mary Poppins made its transition from pages of a book to the silver screen.

Helmed by John Lee Hancock, the flick highlights Walt Disney (played by Tom Hanks) and his efforts to persuade author P.L. Travers (Emma Thompson) to hand over the film rights for the classic book, involving a magical English nanny who looks after the Banks family.

Inspired by true events, the trailer gives a sneak peek at the rocky relationship between Disney and Travers, as the latter grapples with introspective quibbles regarding broadcasting personal tie-ins from her story onto the big screen
