To me, he looks sort of like a relative of General Franco. Scary thought.
I don't think a Franco type character would go to Japan after the war to seek reconciliation after having been brutalized and tortured in a Japanese prisoner of war camp, so looks can be deceiving.
I actually don't think they look very much alike, especially not when they were younger. There's more of a resemblance when Franco gets very old, I think, and there are some bones finally showing. Before that he looks sort of "podgy" to me. (How's that for a forensic anthropology description? :grin
He also has a different mouth, nose, and even more different eyes, so large and dark...the pigmentation is darker all around, in fact.
Sometimes I think all old people start to look alike.
I do think that there is some overlap between some Italians and some Spaniards. I don't know why they don't come to my mind all that often when the question arises in these kinds of games about where some people can pass. Probably it's because I go to France so often, and we have so many Balkan immigrants in Italy that those comparisons occur to me more frequently.
For example, of the two I think Miguel Catalan looks more like Zamperini
Actually, from certain angles, I think Zamperini has a bit of a look of Tyrone Power, although Power was darker and much handsomer, of course.
