While I liked M.A.S.K and owned most of the toys as a kid, there's one 80's cartoon which I think is begging to be made live action (on top of the others such as He-Man, Bravestarr, Thundercats, Bionic Six, Galaxy Rangers, Pole Position, Jayce and the Wheeled Warriors etc EDIT - forgot Visionaries), and that's Centurions. I look at Iron Man and just think 'Yeah, they could do that so brilliantly now'.
