The BBC uncovers the true story behind the "true" story of SAVING MR. BANKS

The story of how Walt Disney courted P.L. Travers into letting him option the rights to Mary Poppins is brought to the screen in this non-fiction drama starring Tom Hanks, Emma Thompson, and Colin Farrell.

A doting father, Walt Disney (Hanks) promises his adoring daughters that he will bring their favorite fictional nanny Mary Poppins to the big screen. Little does Walt realize that surly author P.L. Travers has no intention of seeing her most famous creation bastardized for moviegoers, a fact that makes keeping his promise a difficult endeavor. Years later, however, when Travers' book sales begin to slow, dwindling finances drive her to schedule a meeting with Disney to discuss the film rights to the beloved story. For two weeks in 1961, a determined Disney does his absolute best to convince Travers that the film version of Mary Poppins will be a wondrous and respectful adaptation, meanwhile the author only grows more convinced that she has made the right move in preventing the proposed film adaptation. Later, just when it begins to appear that the rights to Mary Poppins have slipped through his fingers, the ingenious Disney reflects back on his childhood, and realizes that a sensitive chapter from Travers' youth could be the key to clinching the deal.

Below you will find both the trailer for the new Disney movie and the wonderful BBC documentary that delves even deeper into the truth behind the creation of one of the classic movie musicals of all time.
