I Have No Mouth, Yet I Must Scream? Not an intellectual property I think would cross over well with Kingdom Hearts, to be perfectly honest.
The movie was utter garbage, it's true. Don't watch it. Get someone to cut out every scene with Raul Julia, and paste them all together to watch. It won't really have a plot, and you just don't care. The man made such a fantastic performance that it is just so much fun to watch.
