I remember watching quite a number of TV series that I can't imagine the few TV stations we had back then actually broadcasting. I've been trying to find the DVDs lately, and it's almost impossible to even find a mention of the bloody series, let alone find any evidence they were actually ever dubbed (or broadcast in the netherlands for that matter).
Examples:
Ring Raiders, apparently never had more than the pilot episodes, yet I remember watching that series quite fondly. Those few clips I can find now are quite hammy, but the entire series appears to have never existed now.
Thundersub: an Anime series (japanese title translates as Blue Noah and seems to borrow bits of Battleship Yamato), finding DVDs of the series is damn well impossible, I haven't even been able to find torrents of the undubbed japanese version, let alone the english series. It's as if the whole series just disappeared, and it wasn't even that bad from what I can remember, just over the top.
(I mean, really, a gigantic nuclear submarine that surfaces and transforms into a massive heavily armed carrier, complete with fighter drones and tons of lasers, what's not to love)
EDIT: Seems someone is re-releasing the entire Thundersub series dubbed on DVD, just pre-ordered a set. Lets hope this isn't a scam, site doesn't look that professional.
Will know when september ends. (ships on 30th of September)
