Dope topic, I would like to pose the question that could they be fearful of the fact that in some cases it's not as far from reality in black movies? A lot of stuff in those mob movies were fluffed up to appear more gangster and make shit more interesting. A lot of the narratives that take place in "gangster" black movies either have taken place or could take place. So could it be that it isn't fictional enough for them?
eeeeh... I won't say that's entirely true.
The movie Goodfellas was largely based on true events. The murders in Goodfellas for the most part actually happened except in some cases some of the more gruesome details were left out.
Tommy in the movie was based on Tommy DeSimone (Two Gun Tommy on the streets). Tommy was, indeed, murdered the night he was supposed to be made just like in the movie, and he was shot in the head three times. What was left out of the movie was that Tommy murdered not one, but two made men and tried to rape the wife of another made man along with showing his face during the heist also portrayed in the film (1978’s historic $6 million heist -
https://en.wikipedia.org/wiki/Lufthansa_heist ) before the Gambino and Lucchese family heads ordered his death. In the movie they said they gave him a closed casket burial, in reality that didn't happen because his body has never been found. Incidentally, it was John Gotti who put those three bullets into his head.
The lone Black associate in the movie, Stacks, was based on Parnell "Stacks" Edwards. This one they pretty much nailed spot on he was killed for exactly the reason laid out in the movie.
The made man Tommy killed in the movie was Billy Batts, based on real life made man William Benventa, and he was killed for the same reason in the movie; a sideways ass comment about Tommy being a shoeshine boy. The bigger reason, however, was that Benventa's loan sharking business was taken over by Jimmy Burke while he was in prison and he wanted it back.
Every character in the movie was based on a real person and everyone that died is dead and the vast majority of those deaths happened either in the way shown in the movie or worse.
Same goes for another mob flick directed by Scorsese, Casino. (
