Most people are probably familiar with Mary Poppins, the film — but many may not realize that Walt Disney himself spent some twenty years trying to secure the motion picture rights to the original book from its author, Pamela Lyndon (P.L.) Travers. And it's the end of this tumultuous journey that's dramatized in director John Lee Hancock's Saving Mr. Banks — with Emma Thompson playing the no-nonsense author and Tom Hanks as the affable Walt Disney, who's adamant about keeping a promise to his daughters, by bringing their favorite book to the big screen. With its many callbacks to the 1964 Disney classic, especially its memorable songs — it's those fans who will get the most out of Saving Mr. Banks. But if you aren't familiar with that beloved film, this film might just spur your interest to discover what all the fuss is about.
