Keith David has one of the most used voices in American media, narrating documentaries, voicing games and animation, and appearing in more than three hundred credits.
For John Carpenter he is Childs in The Thing, whose final scene with Kurt Russell is the most argued-about ending in horror, and Frank in They Live, who fights for six minutes to avoid putting on a pair of sunglasses.
Platoon, Requiem for a Dream and Crash fill out the dramatic work.
He trained at Juilliard, has won multiple Emmys for narration, and works more or less continuously.
