With the success of Shazam!, Filmation ramped up its live-action output in 1975. We have previously discussed Ghost Busters & Uncle Croc's Block, which were both cancelled after 1 season. Now, it's time for Isis.
CBS & Filmation paired Isis with the returning Shazam! in a 1-hour block, with the Kroffts' Far Out Space Nuts blocking Ghost Busters from making this a 90-minute package from the studio. As it is, the Ghost Busters, despite the poor ratings, served as a lead-in to Fat Albert, which occupied the noon slot back then.
Here's the intro:
Isis, while a daytime series, opened the door for a pair of primetime heroines a year later, as ABC spun The Bionic Woman off from The Six Million Dollar Man, and, on their 3rd try, green-lighted Wonder Woman.
The series is available on DVD, if you can find it.
