Saving Mr. Banks (2013)
No one's hidden pain may be left undocumented these days, and most creative works end up being skinned so that the inner workings of their makers' tormented minds can be laid out on the operating table for inspection. This urge may throw some new light on the activities of characters in a story like "Mary Poppins," where the internalized pain and regrets of a young Australian girl can be seamlessly projected forward onto the book she wrote in later life, lending resonance to every poignant plot point. But it's a strange modern way to interact with art, which has historically been expected to present a mirror to your own personality, rather than provide a hotline to the one buzzing in the head of P. L. Travers. Plus a lot of immortal literature for young people was written by mature individuals with issues, and what does it matter? Look at Enid Blyton; the definitive film about her would have to be made by Wes Craven.
