In Saving Mr. Banks, Walt Disney tries to convince P.L. Travers to let him make a movie out of Mary Poppins. In this clip, he takes his first big step.

Disney (Tom Hanks) greets Travers (Emma Thompson) in his Southern California office and is filled with happiness as she follows along in his office with skepticism. He asks her to address him as Walt because he doesn’t like being called “Mr. Disney.”

You can watch the clip over on EW, who doesn’t allow embeds of exclusives.

The film’s first trailer was released in July and is packed with moments that will make you smile. There’s a scene in the movie where Travers is taken to Disneyland by the man himself. The cast and crew actually shot at the original theme park located in Anaheim, California last year. Saving Mr. Banks is the first film to depict Walt Disney.

Read’s the films official synopsis:

When Walt Disney’s daughters begged him to make a movie of their favorite book, P.L. Travers’ “Mary Poppins,” he made them a promise—one that he didn’t realize would take 20 years to keep. In his quest to obtain the rights, Walt comes up against a curmudgeonly, uncompromising writer who has absolutely no intention of letting her beloved magical nanny get mauled by the Hollywood machine. But, as the books stop selling and money grows short, Travers reluctantly agrees to go to Los Angeles to hear Disney’s plans for the adaptation.

For those two short weeks in 1961, Walt Disney pulls out all the stops. Armed with imaginative storyboards and chirpy songs from the talented Sherman brothers, Walt launches an all-out onslaught on P.L. Travers, but the prickly author doesn’t budge. He soon begins to watch helplessly as Travers becomes increasingly immovable and the rights begin to move further away from his grasp.

It is only when he reaches into his own childhood that Walt discovers the truth about the ghosts that haunt her, and together they set Mary Poppins free to ultimately make one of the most endearing films in cinematic history.

Saving Mr. Banks opens in select theaters December 13 and everywhere on December 20.
