Because Shazam! shared the same network, studio and timeslot as The Secrets Of Isis, the lovely JoAnna Cameron made appearances as the superheroine Isis in three episodes, as well. (And the noble Captain returned the favor, guesting on an episode or two of Isis the same season.)
The new 3-disc, Manufactured-On-Demand Shazam! - The Complete Live Action Series from Warner Archive includes all 28 episodes, presented in their original 4x3, 1.33:1 "standard" TV aspect ratio. Picture quality is generally pretty good for a nearly 40 year-old, low-budget show shot on cheap film stock. Given the source material, the image is grainy and overall a bit soft, with occasionally faded colors. Some episodes look better than others, but there is no significant print damage or other distracting age-related artifacts. Audio is a serviceable Dolby Digital Mono.
