Gastone Moschin, Italian actor perhaps most famous in the United States as “Don Fanucci” in “The Godfather Part II”.
Oddly, I had never seen Part II until just a few weeks ago: I’d seen Part 1 a couple of times, but for various reasons had just never watched Part II. I think, as a movie, I liked Part I better: some of the early stuff with the young Don Corleone is kind of weak.
But maybe the conventional opinion is right, and the two movies should be thought of as a single film about the tragedy of Michael Corleone.
