The Oscar-nominated movie, starring Ray Liotta as Hill, sparked controversy on its release 20 years ago (1990) for its graphic scenes of violence and its brutal portrayal of life in the Mafia.
But Hill, whose biography Wiseguy was the basis for the movie, is glad it has such a reputation - because it shows the downside to a life of gang crime.
He tells AMNY.com, "I think most (youngsters) didn't want any part of that lifestyle. People have told me... they wanted to be gangsters, but when they saw that movie that had a change of heart."
Hill also admits he now regrets his years in the mob, adding: "It was a lot of fun and exciting, but it wasn't worth the price I had to pay with my conscience and dealing with the demons."
