Disney knew that remaking “Snow White and the Seven Dwarfs” as a live-action musical would be treacherous.

But the studio was feeling cocky.

It was 2019, and Disney was minting money at the box office by “reimagining” animated classics like “Aladdin,” “Beauty and the Beast” and “The Jungle Book” as movies with real actors. The remakes also made bedrock characters like Cinderella newly relevant. Heroines defined by ideas from another era — be pretty, and things might work out! — were empowered. Casting emphasized diversity.
