Disney Princess idea #1: "Rumpelstiltskin" movie
I'm surprised Disney never adapted this. Well, I suppose not THAT surprised in modern climate of preference for original films, but that chip on their shoulder seems to be the only problem. Between Jennifer Lee's statement of wanting to do a film about a mom and Josie Trinidad's emphasis on a mom story for "Hexed" (which I imagine is part of why Jennifer Lee greenlit the film), I'm surprised this was never on the table.
Here's what I'm thinking: Rather than simply covering the events of the story, the first act of the film ends with an alternate ending to the fairy tale, with the queen being unable to guess Rumpelstiltskin's name--or maybe she learns that name, but it's not his true name, and he takes her child. The story is about her venturing to rescue her child, knowing the only thing that can defeat/banish Rumpelstiltskin is knowing his true name.
I'm really digging a psychological idea of this film; several Disney films involve child abduction, but it mainly shows how it affects the child over the parents (if still alive), and I 100% think this should take heavy influence from the 1986 film with mind games and a shapeshifting antagonist. I've also had the idea that any time Rumpelstiltskin shapeshifts, he takes on a twisted version of previous Disney protagonists. Also removing romantic subtext; aside from it being a very hard sell to romantically tie the queen and the creature that stole her child and manipulated her, it's also another tag in the "recent Disney male love interests are trash who need to be changed" trope that I'm very tired of. I imagine the king can still be the love interest--though the foundation of this story would obviously need to be changed; the protagonist's father doesn't get her into a terrible situation, and the king doesn't threaten her with death several times and then marry her. Also, am I crazy for thinking they can take some influence from "The Legend of Zelda"? I think the protagonist can be one of the more mature, serious leads; she's used to a life of labor (in the fairy tale, she was a miller's daughter, though I could also see her as a farmer's daughter) and is kind of shocked by how she manages to win the hand of a prince, and then her child is stolen. It's a lot to take in--but when she locks in, she's ready to fight, and has some athleticism.
Concerning the setting, I think it can be pretty open; I think the fairy tale references the protagonist having blonde hair to reference the gold she's supposedly able to spin, but most of the European princesses are blonde. I'm ready for a dark-haired European princess. Perhaps a Slavic/Eastern European princess, or a Hungarian princess. Or we could do like "The Princess and the Frog" and adopt the story for a non-European culture. I'm not averse to another American setting, but perhaps that'd be too soon and feel too similar to TPATF.
For the creative team, I need the Anderson-Lopez team to have something else besides the "Frozen" franchise, and they made some of my favorite songs associated with fairy tale films. For directors, I'd definitely look at Trinidad or Lee to do it given their passion for a motherhood story (though I've heard on the "Frozen" fanbase that Jennifer Lee isn't that great, and with Josie Trinidad demoted to co-director for "Hexed," I'm curious as to what her creative voice is like).
Honestly it would be interesting to see if Disney could make a Disney princess film out of this; given how many of the princesses are marketed as role models and the whole Cinderella blue dress controversy was rooted in concerns of marketing a wedding dress to girls, I am curious if Disney would be controversial for having a Disney princess who's a mom (in her official theatrical film). Plus the age would be controversial as well; if she's around the age as many princesses, there's the whole controversy of "you're advertising for our daughters to have kids young" and if she's made older (ie 30s), then she feels "too mature" for the line. Screwed if they do, screwed if they don't.
