I'm not sure how great his range is as an actor.
He says that when he puts on the wig - he becomes the character. David Chase definitely spotted something.

I like the way he moves - hunched and the frowning expression that Silvio normally has on his face. Like De Niro, he can frown with every single muscle in his face.

He's at his best doing those Al Pacino/Michael Corleone impressions or posing as he tries on new clothes like his golfing shoes in the first episode of Season 2 nodding his head and sneering.

Not only does he love movies, I think Silvio would like to be Michael Corleone even more than he would like to be Al Pacino and that's reflected in his style.

What the Godfather would have made of Bada Bing - I don't know!!!!!!!!!
