I'm not quite sure it's a spy movie per se, but it's a lot of fun. I hope that Dorado Films does release this on a proper disc, as I've only ever seen it in it's fullscreen form. our hero isn't working for an agency though. he's a knight of England... Sir Reginald Hoover.
there were several superhero movies made in the midst of the Batman/007 craze of the mid sixties and this is one of them. I do wish I had seen this as a kid, along with the others, like Superargo and Goldface. I would have loved it.
