Which Award Season Movies Are Based on a True Story?

The Real Story: Tom Hanks and Emma Thompson's latest feature is based on the real-life story of Walt Disney's quest to turn P. L. Travers's book Mary Poppins into a film.

How the Movie Differs: The film portrays Travers as being tart and difficult to deal with, and, according to various reports, that much is true. However, the movie does gloss over some interesting parts of her life, like that she allegedly had a lesbian relationship with Madge Burnand, a woman she lived with in England. There's also the rather unsavory fact that she adopted a young boy named Camillus but refused to adopt his identical twin brother, Anthony, despite his family's pleading.
