He's barely made his first appearance in the film when he swaggers over to a group of other men and hoists his jeans up by the belt, ensuring that his bulge will stand out!
He played a fireman in another episode and then still another (uniformed) policeman in a fourth. His uniform pants seem to be making an impression here.
Lex Barker, eager to shed his Tarzan image, had done so in Germany and body-building marvel Steve Reeves found great success in Italy as Hercules.
With age, he began to thicken out a tad in the face and physique. I think he looks even better than before! Apart from the strong man spectacles such as Hercules the Invincible and Hercules Against the Barbarians (both 1964), he also began to star in spy films. The success of Dr. No in 1962 had spurred a mountainous wave of imitators, many of which were made in Italy and surrounding countries.
In 1967, he costarred with Irina Demick in the comedic spy-romance Tiffany Memorandum, ironic since she was the girlfriend of his long-ago boss at 20th Century-Fox, Darryl F. Zanuck! His role in this was Dick Hallam.
During a temporary return to the U.S., he filmed a bit role as a flower man in Gene Hackman and Ann-Margret's Twice in a Lifetime (1985.) He also popped up in the Italian-made sci-fi flick Arena in 1989.
