Commando Cody, Sky Marshal of the Universe? Designed as a tv-series, but also played at some theaters as if were a serial, right? Self-contained episodes as I recall, not serialized. A Republic production, with not to many episodes, akin to their “Fu Manchu” series. Strange that Republic never got all that big into tv production.
Yet the outfit is the same as “King of the Rocketmen” (1949), which was patently a serial. Same character? Always a tad confusing to me.
Sat this as a Saturday morning serial on the mid 50s.
