He doesn't look like any Sicilian I've ever seen-- he looks like an Aryan agent of death.
Depending on what race conquered what part of Italy in the dim and distant past, there are lots of blonde/blue-eyed [and red-haired] Italians, same as with Spaniards but Michael doesn't 'look Italian' to me either.
[maybe he takes after his mom, "Ilsa"]....LOL!
Maybe he is only half Italian.
I thought that, too.
