I'm surprised a veteran historical re-enactor like yerself would mistake a Roman outfit for a Carthaginian one, Grecchus. And you with that Latin handle 'n all.
Somewhere I have a jpeg I pulled off the internet of Robert Mitchum as a knight in armor that beats this shot of Mature by a mile. Unfortunately, I couldn't find a webstie that still has it to link to, nor could I find a film in his history at IMDB that seems to match this shot.
