“Saving Mr. Banks,” the story of Walt Disney’s effort to create “Mary Poppins,” opens nationwide this weekend (Dec. 20). The film tells the story of the tough courtship between Disney (Tom Hanks) and Pamela Travers (Emma Thompson) and the story-telling/songwriting efforts of Robert and Richard Sherman.
Richard Sherman, who won the song Oscar for “Chim Chim Cher-ee” and the Oscar for the film’s score, shared stories about the creation of “Mary Poppins” with director John Lee Hancock, “Mr. Banks” composer Thomas Newman and BMI VP of Film TV Doreen Ringer Ross at the Billboard and Billboard/THR Film & TV Music Conference this fall.
Sherman shared a story about the film’s bets-known song. “As kids,” he said, referring to his brother, “we used to make up words so we said let’s give the kids a big obnoxious word. It’s a British thing so we used atrocious. Then precocious. What rhymes with that? Why not docious? Then we started with colossal, hit cali-fragile, said ‘that’s good’ and two weeks later we had "Supercalifragilisticexpialidocious.’”
