One method of torture depicted extensively in the film involves hanging individuals upside-down from their feet and lowering them into a narrow hole dug into the ground.
Several different torture methods are used throughout the film, including some involving boiling water, bleeding, drowning/waterboarding, and crucifixion.
There is also a decapitation scene during which they don't shy away from showing the head and body with a long, thin trail of blood. The movie is more disturbing than gory, as it revolves around torture.
