Mel Gibson’s “Hacksaw Ridge” tells the story about American combat Pfc. Desmond T. Doss, who amazingly saved men without using one bullet in one of the bloodiest battles in WWII. The unarmed Army medic saved the lives of 75 fellow soldiers under fire on Okinawa Island. Doss had one weapon—this was a simple prayer before going behind enemy lines under heavy artillery.

“Desmond Doss distinguished himself beyond any normal reason in World War II,” producer of the biological film Bill Mechanic said. “He was the first to win the Medal of Honor. Desmomd came back from the war and he was a humble man and did not believe in publicizing himself. He didn’t want to sell his life rights.” But friends in his church encouraged him to do it. Doss finally agreed and did a documentary called “The conscientious objector.” The film interested Mechanic because Doss’ faith really carried him through.

Mechanic said that Doss was a real life super hero. “You always hear about a father saving his son or daughter by lifting a car, which is not possible for most people to do. This guy lifted 75 cars in a sense. He was in Okinawa on top of the escarpment and the American troops were overrun by Japanese and they retreated. He was the only guy who wouldn’t leave.”

Doss didn’t believe in using guns. He spent 16 hours pulling men out of the battlefield and out of view of the Japanese killing team looking to find soldiers who were alive. The Virginia native was driven by his faith, and now it is a legacy. He was awarded the Congressional Medal of Honor for his heroism.

Doss was criticized for not carrying a gun by the very men he saved. He knew the war was necessary but didn’t want to kill under any circumstance. “He was considered a hero among heroes,” offered Mechanic.

This was Gibson’s first directorial since “Apocalypto” in 2006. “Hacksaw Ridge” opens on Oct. 4.
