According to TMZ, Dr. Dre never asked Suge Knight for permission to include him in the N.W.A biopic, 'Straight Outta Compton,' which may have led to the murder of Terry Carter.
Knight wanted to talk to Dre about how he was being portrayed in the film, and this meeting was set-up by friend Terry Carter. The sit down never happened because, according to their sources, Knight got into a fight with actor Cle "Bone" Sloan, which led to him eventually backing over him and Terry Carter in the parking lot.
As you can see in the screen shot from the trailer (above), it looks like Suge Knight's character is in an altercation with somebody in the studio.
Knight was charged with the murder of Terry Carter, attempted murder of Cle Sloan, and hit and run. His bail hearing was recently moved to March 20, which means that he will have to remain in jail until then.
