Newman's radio writing included scripts for Escape, Suspense, and The Halls of Ivy as well as the first broadcast episode of Gunsmoke.
He is not officially credited for his screenplays for The Magnificent Seven and The Great Escape, having renounced credit after sharp disagreements with the director, John Sturges in both cases, over changes made during shooting.
Newman was born in New York City. He died in Sherman Oaks, California, a suburb of Los Angeles, on 14 October 1993.
