Saw family enforcer on youtube real name of movie when it was released was Death Collector starred Joey Cortese. Frank Vincent and Joe Pesci were also in it. Nobody knew who Vincent and Pesci was when it first came out in the movies.

Pretty good copy on you tube I saw it in the movies in the 70s. I thought Cortese would be star back then.

When they were shooting it Pesci and Cortese had a real fist fight. The guys on the set had to break it up. Pesci told me he was kicking cortese’s ass. Cortese much later said that it did not happen. I called up the wise guy show remember that radio show starred big pussy from the sopranos. That day he was absent and Frank Vincent took his place for that show. Vincent said as far as he knew it never happened. But later a guy from the set said the fight did happen and Pesci was telling the truth he was beating on Cortese.
