The scene where O-dog, Kane and Wax jack those fools at the burger stand and the final drive by scene are a lot bloodier. When it came out though it was before all the "unrated" stuff was comin' out so I think that's why it was labeled as "NC-17". I've seen a lot more gore on R rated movies than was added to the effects on this version. They also had Harolds funeral and a scene where stacy and charif (not sure of the spelling) showed up and talked to Kanes grandparents about him moving with them, right after he got outta jail and was in the bathroom pukin'. Other than that, I really didn't notice too much more.
There's other shit in the previews that wasn't put into the movie so there'll probably be a directors cut out in the next 10 years. LOL
