Don Vito Corleone
Elite
I'm also intrigued by the intro claiming that it's a true story. In the first season, they made repeated reference to what happened 20 (or however many) years ago. So the implication is that this is going to be similarly surreal but based on actual events.
That intro was shared with the movie. It was a joke by the Coens in the original movie and the show is paying homage to that. None of them (the movie or either season of the show) was actually based on real events.
