It's more about Eazy actually owning and starting a label which is more boss like than a chuck d story. NWA has a longer legacy as far as offsprings pe cannot compete with that.
This is true to a degree, but not that simple, either. First, Chuck D was the first one to tell a major to take a hike (Def Jam) in order to release music directly to the internet in the form of
Bring the Noise 2000 followed up by
There's a Poison Going On. So Chuck has owned all of his masters and music since around 2000, and when movies came calling for "Can't Truss It" and "Fight the Power" he went in and re-recorded them in order to utilize those masters for film (like
American Gangster). Chuck has been on the independent grind for years now. And he was one of the first artists to support Napster. PE also created the blueprint for having a live show that could actually deliver in a major arena setting and compete with big rock acts.
PE has had some offspring as well, namely Busta Rhymes (via Leaders of the New School--Chuck D is the one that gave Busta his name). And you could argue that they kept Ice Cube hot when he was at a crossroads (he probably would've been all right, but Amerikkka's Most Wanted wouldn't have been as big of a deal without PE and the Bomb Squad's involvement--they made it a classic).
One thing I respect about Chuck D is that when he goes on tour, he'll often bring along some forgotten rappers and give them some work, and they usually deliver as opening acts. First time I saw PE live, they had X-Clan opening for them and Monie Love.
If I was going to do a PE movie, I would probably look at telling it from one of the S1W's viewpoint or something like that, I don't think I would focus in on Chuck D or Flav. Sometimes I think these biopics err in making us try to see it through the big star's eyes when we can't really get on that level. It's a hard movie to make, because Chuck is notoriously clean living and Flav's antics are kind of too well known by now and cliche for a biopic. I would focus in on the death threats Chuck used to get, the pressure of being made to drop Griff (which he calls his biggest mistake), and of trying to go indy. You'd also have the Europe angle where they went and killed it over there before they made it big in the US. And culminate with them scoring a big hit with "Harder Than You Think" and the rock and roll hall of fame, with some Flav hi-jinks mixed in between just like he's mixed in on a PE album.
