The resemblance is uncanny: Tom Hanks suits up (and sports a mustache) to portray the legendary Walt Disney in the upcoming movie Saving Mr. Banks. In the first official still from the film, the actor shows author P.L. Travers (Emma Thompson) around Disneyland in Anaheim, Calif.
When Disney's daughters begged him to make a movie of their favorite book, Travers' Mary Poppins, he promised to deliver. It took him 20 years to obtain the rights -- and when he did, he was forced to deal with its curmudgeonly, uncompromising author. "She's the most difficult person I've ever played," Thompson, 54, tells TIME of her character. "She was a woman of quite eye-watering complexity and contradiction."
"Often I play people who are controlled by some very clear guiding moral principles," says Thompson, a two-time Academy Award winner. "There are very clear moral prisms these women pour life through, and I understand that very well. And [Travers] was not like that at all. She was far more chaotic and confused and morally various."
