He owned a printing compnay, and got into trouble for some of the methods he used to collect money owed to him. There is a scene in the film, you may recall, which draws on his personal experiences in this area.
He was tried and found guilty, and I think the film was produced either while he was awaiting sentencing or appealing; I'm not sure which.
That's funny that you also saw it twice, Letizia. The first time, I took my teenage son who is really into the genre. The second time, I took a friend who I knew would really appreciate it because (let's just say) they're "familiar" with the lifestyle.
True, by no means can you compare it with big budget movies like "The Godfather", "Goodfellas", or "Casino", but for a low budget indy film, you can't beat it.
I though there were two really memorable scenes: The one in the Chinese restaurant where they're sitting around talking about the time they had to collect money from some guy who was really big, and they say something like "It was like the line in the movie. We needed a bigger gun."
Also, the scene with Pat Cooper as the lawyer. He practically stole the picture.
