Michael B. Jordan needs to ugly himself up if he has any hope of playing Russell Simmons in the Def Jam biopic ... so says Russell Simmons himself!
We got the Def Jam co-founder out at the Dolby Theatre in L.A. Wednesday night, and he not only gave his thumbs up to Michael B. ... but he thought Jonah Hill would make a great Rick Rubin.
Universal is making the flick, which Russell is producing. Sounds awesome.
