Desmond T. Doss was a Seventh Day Adventist from Virginia who agreed to join the Army in the Pacific in World War II but refused to fight. He became a medic and on numerous occasions ran across the battlefield to save injured soldiers in the midst of rifle fire, machine guns, grenades and artillery. He is credited with saving 75 men in one battle. He was injured himself numerous time receiving three purple hearts. On one occasion he rolled off the stretcher so a soldier hurt more badly than he could take his place.

Private Doss was a legend in his battalion for gallantry. He received the Congressional Medal of Honor -- the first to do so as a "conscientious objector" (someone who refuses to fight on religious or moral grounds).

Doss died in 2006 and a movie about his heroics has been in the works for over a decade.

Garfield definitely looks the part, and has earned the admiration of audiences for playing characters with deep moral convictions placed in difficult situations where ethical choices must be made.

Gibson has earned a reputation for making violent, gory depictions of battle that shock audiences into admiring the bravery of soldiers. The two working together should be interesting.

The movie will be called "Hacksaw Ridge" and is due out in 2016.
