While we're on the subject of the Hulk and marvel in general, it's a different animal altogether now. Marvel characters are fully developed properties that have been fleshed out over the years in comics, cartoons, movies, merchandise, and tv shows. When Disney originally developed 20,000 leagues, Snow White, or most of the others, the only exposure they had, was, for the most part, written. A book. Adapting the Hulk or Iron Man to a Disney style of storytelling would be impossible. These characters were purchased for the demographic they brought, not because they lend themselves to "Disneyfication". They don't NEED to be embellished with any Disney touch. But when people think of Snow White or Mr. Toad, it's the Disney version they think of, not a work of classic literature.
