OK, I admit that I am not an expert on this actor but I think there must be some confusion here because in my opinion we have pictures of several different actors here!
I am not so sure that it is really him in Io e mia sorella
, and I am very, very sure that it is not him in both Da Corleone a Brooklyn
and La moglie in vacanza... l'amante in città
. I just don't think it is possible that it is him. Or maybe I am crazy?? What does A.N. think?
For comparison, here are some more pictures of him from Roma a mano armata
And a little better look at his face in Quelli della calibro 38
