There is a lot going on in this movie, and we cover a lot of ground with our hero, Roger Browne, who is agent Gordon. Browne also starred in a number of the sword-and-sandal epics of the early 1960's; he was a very big, very fit guy. When he punches anyone, you're kind of surprised that it ever takes more than one punch to knock them out! Basically, Browne gives the impression that he could whip his weight in alligators, and then some.
A nice thing about Browne, is that he often shows a rather sly sense of humor; you get the idea that he is enjoying himself, indeed, when he is flirting with some of the beautiful women in this movie, who include top Euro-spy stars Rosalba Neri and Helga Line.
I will say, a plus for this movie is that you can't always tell what is coming next, in my opinion. At least I couldn't. Roger Browne was one of the main leading men of the Euro-spy genre, and he was a good and important figure in it. Any Euro-spy movie with him starring in it is worth seeing and provides enjoyment.
