As anti-violence restrictions that had been in place since 1968 were either being abolished or eased out, a doorway was opened for a return to swashbuckling adventure, the likes of which hadn't been seen since '68's Arabian Knights. Fortunately, the newest series of this kind came from the same studio.....
The Pirates of Dark Water began as a 5-part miniseries that aired on Fox in February 1991. However, 7 months later, the series moved to ABC, with the miniseries encored over the first five weeks. It was also the first---and to my knowledge, the only---series created by David Kirschner ("Child's Play"), who was with Hanna-Barbera at the time.
Dark Water's central plot centered on Ren (George Newbern) and his battle with Lord Bloth (Brock Peters), while at the same time trying to save Mer from the titular menace, the dark water that threatened to consume Mer.
In an interesting turn of events, when the series changed networks, Kirschner and his casting directors made a change with Nibbler, Ren's sidekick. Originally voiced by the inestimable Roddy McDowell, the role was recast with Frank Welker dubbing over McDowell's original vocals.
Now, here's the intro:
The early success of the series led to a 9-issue comic book, published by Marvel, but the show ended without Ren and his crew finishing their quest. The series was cancelled in 1993 after 2 seasons.
