In a 2020 interview, actor Richard Harrison said "he thought this movie was one of his best efforts". I totally agree. I first saw this movie in Italian in 1978 and have since found two addition copies in English. Edited together they make up a pretty good story. Perhaps the "other" negative reviewers have not seen a complete version? Steve Norton chases around Europe trying to get back millions of stolen diamonds. Living life in the fast-lane with gals and fancy hotels, he chases lead after lead in Malaga, London and Rome. He even has time to S. C. U. B. A. Dive. This is a very enjoyable movie to watch.
