Matthew Cherry and Geno Brooks are two on the rise writer/directors
Matthew Cherry is responsible for the EXCELLENT short lived web series Almost 30, and a couple of indie dramas. I think he'll be one of the black male directors who blows up similar to Ryan Coogler in the next few years...
Geno Brooks is a fukking genius. Dude has his OWN subscription based web channel (similar to Black & Sexy) where he writes/directs/and produces his own shows. All of them starring a predominantly black cast. Check out the site
