Staten Island isn't Manhattan. Location, location, location, as they say.
I wonder if they've left anything inside to match the way it was during the filming of the Godfather movies. I ask because I was in Sicily this spring on a tour, and of course, the bus had to stop at the bar where Michael meets Apollonia's father. It was closed for renovations, but the tour guide said that it had prospered greatly as a tourist attraction after the movie. I wonder if any of that happened on Staten Island... but I doubt it.
My understanding is that interior shots were done in a studio.
Someone upthread said the owners of the house had some of the rooms remodeled to match the appearance in the movies.
No, Staten Island isn’t Manhattan. But it’s closer than Scarsdale or Bronxville, making for an easy commute, and it’s more fashionable than it used to be.
That’s really not a very high price for such a house.
