- Gamera vs. Zigra was never picked up by American International Television, as Daiei had gone bankrupt by 1971 and had to distribute the film through Dainichi Films. As a result, no export version could be prepared.
- In the 1980s, distributor Sandy Frank acquired the rights to five classic Gamera films, had new video versions prepared, and distributed them under King Features Entertainment.
- The English dubbing is uncredited, but it was possibly dubbed at Anvil Studios in England. New credits over an ocean backdrop are placed before the prologue, with the "Persistent Pursuit" track from later in the film serving as the main title cue, complete with Lora Lee's "zap" sound effects from the music & effects stems. Additionally, Zigra has been given a masculine voice.
- Played on Mystery Science Theater 3000 twice. (Once in 1988 and again in 1991).
