The young man is Alberto Frezza, born in Milano, raised in Ethiopia, educated in American English schools.
Here he is playing a fireman, Ryan something in an American tv series:
Had never seen the show (I think it's a spin off of Grey's Anatomy), or heard of him, until I stumbled on an interview with Dermot Mulroney (also on the show) who said he thought Frezza looked very much like him. So, I checked.
Dermot Patrick Mulroney:
Alberto Frezza:
His American is completely American, if you know what I mean, which is why he's not relegated to "foreigner" parts, and given his looks and what Americans are sure constitute all Italian looks, he's never played an Italian American to my knowledge. Always Irish/German, Irish, German, etc.
Yet, in this interview, he looks completely Italian: gestures, facial expressions, and yes, even looks.
No, it's not just the tan and darker hair with age.
He's lucky: this chameleon ability is very useful for actors.
To be honest, I don't think he's very good, but the female viewers seem to like him a lot. I think it's because a lot of his own personality goes into the portrayal.
