This is the first I’ve heard of it. I know there was a lot of complaints about The Lion King apparently ripping off Kimba the White Lion, not to mention the whole mess where Jeffrey Katzenberg plagiarized A Bug’s Life with his DreamWorks film Antz, though.
It never made the news. He is just a little nobody small fries and not worth headlines. He filed against them and they were in talks but that’s as far as it got. He had proof with a video of his cartoon but Disney has big time lawyers.
