After years of seemingly no progress, the long awaited sequel to The Mysterious Cities of Gold has arrived. Sort of. Basically the new footage is in French.
I fondly remember watching it when it first came out.
I remember this show being on Nickelodeon, but hardly watched any of the episodes. And I should have since the premise is right up my alley as it supposedly involves ancient astronauts and such. I know it was an Anime originally. Is it by any chance available on DVD?
Yes, as a DVD box set.
I got the DVD set of the original series last year! 
Used to love it as a kid during the 80’s.
This new series looks really good. I hope they dub it in English!
