War doesn't just need soldiers, it needs saviors. Andrew Garfield takes on the real-life story of heroic U.S. Army medic Desmond Doss in "Hacksaw Ridge," the World War II drama from director Mel Gibson coming out this November.

Doss was a Seventh-day Adventist who didn't believe in carrying a weapon or killing. But he wanted to use his skills to help, so he became a medic and enlisted during WWII, saving 75 men -- without firing or even carrying a gun -- in Okinawa, during the bloodiest battle of the war. He was the only American soldier in WWII to fight on the front lines without a weapon. He single-handedly evacuated the wounded from behind enemy lines, and was injured by a grenade and hit by snipers. Desmond Doss became was the first conscientious objector awarded the Congressional Medal of Honor.

Lionsgate just released the first trailer for the film, co-starring Sam Worthington, Luke Bracey, Teresa Palmer, Hugo Weaving, Rachel Griffiths, and Vince Vaughn. Yep, that's a lot of Australians (with a Brit in the lead role) for a story about U.S. soldiers, but Gibson directed the film in Australia, so there you go.

Watch the trailer:

It is truly an amazing story, and a pretty timely one as the U.S. continues to debate war and guns. "Hacksaw Ridge" is scheduled for release November 4, which is just in time for Oscars consideration.
