Gary Graver was an American film director and cinematographer. He was a prolific filmmaker but is best known as Orson Welles final cinematographer. Under the pseudonym of Robert McCallum he also directed adult films.
Graver was born and raised in Portland, Oregon. In high school, he produced and starred in his own radio show, and had built a movie theatre in his parents basement where he showed his own films. At age 20, he moved to Hollywood to become an actor, but drifted into production when work as an actor was scarce. He was drafted into the U.S. military and was assigned to the Navy Combat Camera Group. After returning to civilian life, Graver made documentaries for a year before starting to work on larger budget features.
