Oh goodness. They've done a lot of movies I've liked.
Pretty sure they're involved with Warhorse, which I loved, though idk if I'd really call it my favorite, but if it IS Disney, I might.
I absolutely loved UP, which is technically PIXAR but Pixar is owned by Disney...
One Disney movie that's one of my all time favorites that no one here will have heard of is called Sylvester. It's an old horse movie about an orphan ranch hand who trains a wild stallion to be a champion event horse and they go to the Rolex three day event in Kentucky (a childhood dream of mine lol) idk. It's the sort of movie that's pretty terrible to everyone who isn't a horse person, but that horse people love because we love watching horses haha.
Sooo. Long story short, Sylvester is probably it for that.
