The film was originally a pilot for a weekly ABC series that failed to make the network's schedule. It was broadcast in the United States on January 15, 1972 and then released in other markets as a feature film.
Time Out London said, "Lots of exotic sets and outlandish secret weapons, just a pity it's all rather old hat Bond stuff. Still, with Denholm Elliott giving sterling support as her sycophantic aide, Davis has a ball with some genuinely monstrous lines."
