My friend Charleson Mambo showed me this You Tube video. It looks that it's a DVD copy from an original VHS from a TV show in the 80's. Yes, they committed the ultimate sacrilege. They made a 'Watchmen" Saturday Morning cartoon. This is the opening.
Actually it's a parody made by Harry Partdrige. He is very talented. The funny thing is, if Alan Moore would have sold out in the 80's, this could have been a reality!
