Cartoon Network and The Donners' Company were working on a cartoon version of The Goonies that would have picked up right where the movie left off. It was going to incorporate all the deleted scenes from the original (like the Gorillas, Leeches, etc.) along with new adventures.
The latest word on what has stopped the production is that the cast wanted too much money for their likeness. We heard the first contract was rejected (this isn't uncommon in the industry), but no follow up was made by Cartoon Network to work something out. Let's remember that the original cast makes nothing from all the Goonies DVD's and TV showings that continue to sell today, so I'm sure all they wanted was a fair share of the profits. Hopefully they will work something out in the near future. We will keep up on this if something develops.
