Trailer premieres for Mel Gibson's 'Hacksaw Ridge' starring Andrew Garfield

LOS ANGELES, July 29 (UPI) -- In the trailer for the upcoming Mel Gibson-directed Hacksaw Ridge, Andrew Garfield stars as Desmond Doss, a conscientious objector who refused to fight during the Battle of Okinawa.

Based on a true story, Doss -- a Seventh Day Adventist -- refused to fire a weapon during the Battle of Okinawa in World War II. Instead he single-handedly saved the lives of 75 of his fellow soldiers without firing a shot.

Doss was awarded the Medal of Honor by President Harry S. Truman for his life-saving efforts.

The movie also stars Hugo Weaving, Sam Worthington, Vince Vaughn, and Teresa Palmer.

Hacksaw Ridge hits theaters on November 4.
