Sean Price's story could be interesting, especially (and sadly) since his unexpected passing. I've been a BCC stan since day one and admittedly the amount of love he's recieved and admiration given surprised me. A biopic on him and those crazy Brooklyn Decepticon years could be interesting. A movie chronicling his wreckless youth, his Heltah Skeltah days, going on drugs with Rock and disappearing from the scene, becoming Muslim, enjoying a cult like following as a solo artist, until his untimely death could make for a good movie.
Guru's story could be interesting too. A kid from a middle class if not upper middle class background from Boston, earns the respect of Brooklyn heads during the 80's/90's and becomes a prominent emcee who's part of a legendary group that is Gang Starr. Gang Starr goes on hiatus and Guru works on and completes critically acclaimed Jazz infused albums. Both he and his band's experiences on the road and especially in Europe would make for good scenery. Not to mention addressing where Solar came from and the nature of his relationship with Guru. Then the movie would ultimately have to tackle the issues surrounding Guru's death.
