- Exiled from Continuity: Sony's ownership of this serial and its predecessor ensured that Warner Bros. wouldn't stream it on their DC Universe app, a fate shared with the 1966 series and its tie-in movie (owned by Disney/20th Century Fox).
- Name's the Same:
- No Budget: By far one of the cheapest serials ever made, due to being made by Columbia during the tail-end of the format's commercial viability.
- The locations consist of the same ten redressed sets (including a hallway used for two different buildings and a "cave" which doubles as both the Batcave and the Wizard's lair), two exterior locations (Carter's house and the research plant), a studio backlot for city scenes, and a huge stretch of dry California road.
- The "Batmobile", likewise, was the most inexpensive contemporary car they could get — a factory-stock Mercury convertible painted maroon; since the '49 Merc was bad at handling sudden curves, the production went through about six during shooting, and would merely switch out one car for another when it sustained damage.
- The one complex special effects shot — of Jimmy in the Batman suit falling to his death — was recycled from the 1943 serial. Other effects range from typical (negative scratches used for energy rays) to laughable (the invisible Wizard's gun held up by a string) to downright embarrassing (a radio-controlled toy truck being treated as a scientific marvel).
