Imagine you take the Percy Jackson movies and Eragon movie, warp the protagonist's even more personality and some of the other side characters. Undermine the world building and completely make the main protagonist, who, in the books, is a selfish anti hero into a childish playful kid who has no idea what they're doing. And also get a big beloved studio with the ego the size of Saturn and you have Kenneth Branagh's Artemis Fowl.
