A year prior to this series premiere, Columbia Pictures had new prints struck of their 1943 wartime serial Batman (1943) and released it to theaters, promoting it as "An Evening with Batman and Robin" (1965) All fifteen chapters were shown intact in a single sitting. The presentation ran almost four and a half hours.
The Batsignal shown in the sky did not match the silhouette on the glass - the silhouette had a visible neck, while the projected image did not. Also, the tail was longer in relation to the rest of the image on the silhouette than it was in the projected image.
The actor who played the villain would always be credited as the "Special Guest Villain"
Several three-part episodes were produced with the intention of editing them together for distribution overseas as feature films.
