Filmation had hit its first pothole with their live-action line in 1975, as Ghost Busters & Uncle Croc's Block were both cancelled after 1 season. The studio forged ahead with their 4th entry for CBS, Ark II, but it too would end up a 1-year wonder.
Soap star Terry Lester (Young & the Restless) was cast as Jonah, the pilot of the title vehicle, and leader of a roving research team in this futuristic sci-fi series, set in the 25th century, but nowhere near where Buck Rogers had been, and Buck would later surface over on NBC 4 years later. All of the central characters, including a talking chimp named Adam (voiced by co-executive producer Lou Scheimer), were named after Biblical characters from the Old Testament, but insofar as I knew, there weren't any plotlines with Biblical connotations.
Anyway, Post-Apocalyptic.com uploaded the series premiere, "The Flies", with guest stars Malachi Throne (ex-It Takes a Thief) and Jonathan Harris (ex-Lost In Space), who had co-starred on Uncle Croc and would headline Ark II's replacement, Space Academy, the following season. The opening, unfortunately, has been edited off.
The fact that Ark II had failed suggests that the live-action movement had already peaked, and, in terms of scheduling, things would be back to normal by the start of the 80's.
