The guest star who played False Face, a villain whose face is always hidden behind a mask, is credited only as "?" during the opening credits. The end credits finally list the actor behind the mask: Malachi Throne.
Portions of this episode...particularly the "Abandoned Bioscope Studios" scenes are filmed on the Desilu backlot. The set for Gomer Pyle USMC and downtown Mayberry can clearly be seen.
Although credited as "Midget", "Fat Man" and "Thin Man", False Face addresses these characters by name during the bank vault break in. The Midget is Burns, Fat Man is Brinks and Thin Man is Pinkerton. At the time, these names were associated with Security and Detective agencies. Ironic names for men attempting to break into a bank vault.
At 15:22 of 25:18 minutes, a sign on the fence behind the Batmobile reads "NO TRESPASSING Desilu Studios".
The only episode of the series where a camera was mounted on the Batmobile to show a view from behind the dynamic duo while driving.
