Recreating the Beauty of Saving Mr. Banks

Saving Mr. Banks (2013) was something of a groundbreaking film for Disney. The company had done films based on true stories before, but Saving Mr. Banks was the first to juxtapose the story of a Disney classic's making with the story of the original work's author. Saving Mr. Banks met with critical acclaim and is also one of my favorites in the canon. In fact, I'd very much like to see more films like this.

Do other films in the canon, live-action or animation, lend itself to this type of storytelling? Would actors or viewers be interested in say, learning about the personal lives and struggles behind the makings of Disney's Golden, Bronze, or Renaissance films? Are there untold stories to be mined from animators (e.g,, Walt's Nine Old Men, female animators, etc.) and other production staff/voice actors? Discuss.
