The script of which film is said to be approved by the Italian-American mobster Russell Bufalino?

Wonder if he made them an offer they couldn't refuse

Goodfellas , so brutal, yet so good.

He gave the producers the green light after making them promise they wouldn't use the word "mafia" in. He loved the film when it came out and even changed his mannerisms to match those of Vito Corleone.
