No wonder that this picture anticipates Bond by 25 years, it was co written by Jack Whittingham, who was one of the principle architects of the movie version of James Bond.
Whittingham shares a credit on the film, and the novel, Thunderball, which was originally intended to be the first James Bond picture.
More than a few of the classic Bond tropes are contained in the story--it actually points to Dr No (bringing down planes electronically) and to so many of the Bond stories that have huge battles at the end, with the hero freeing, and/or working alongside troops of one kind or another.
