Lionsgate released the first trailer for Mel Gibson’s World War II drama Hacksaw Ridge on Thursday.

The film stars Andrew Garfield (The Amazing Spider-Man, The Social Network) as World War II medic Desmond Doss, who saved 75 men during the bloody Battle of Okinawa without ever firing a gun.

Doss became the first conscientious objector ever to receive the Medal of Honor — awarded to him by President Harry S. Truman on October 12, 1945 — for his heroism on the battlefield. Doss refused to carry a firearm due to his religious beliefs as a Seventh-day Adventist, often heading into battle armed with nothing more than simple prayers.

Hacksaw Ridge is Mel Gibson’s first directorial effort since 2006’s Apocalypto. In addition to Garfield, the film also stars Sam Worthington, Teresa Palmer, Vince Vaughn, Hugo Weaving and Rachel Griffiths. The screenplay was written by Andrew Knight, Robert Schenkkan and Braveheart screenwriter Randall Wallace.

Hacksaw Ridge is in theaters November 4. Watch the trailer above.
