That movie is the King of quotes. “I want my money! I want my money!” “Now go home and get your shinebox!” “Your going to go dig the hole, I’m not digging the hole” What was interesting is the entire movie was taken almost verbatim from the book. I read the book and it was like reading the script.
The Killer Angels (Gettysburg) is the same way.
Goodfellas, along with The Godfather, is one of the few motion pictures that's as good as the book it's based upon, even though the book itself is riveting.
