I remember getting the figures for M.A.S.K and watching Bravestarr on Saturday mornings,but could not say what either was about.
After seeing how great Transformers turned out I think a lot of 80's cartoons could very well work on the big screen.
Dungeons & Dragons
Thundercats (is being planned for the big screen)
He-Man & Masters of the Universe (a proper one,not like the cheesy (but enjoyable) 1987 film)
The Jetsons (Thought the 1994 Flintstones movie was ok,could of been better written)
Silverhawks
