* "Saving Private Ryan" (1998): This film, set during the Normandy invasion of World War II, features graphic scenes of violence, including the Omaha Beach landing and the D-Day assault on the German bunkers.
* "Apocalypse Now" (1979): This film, set during the Vietnam War, depicts the horrors of combat in the jungles of Southeast Asia. It contains scenes of graphic violence, including the massacre of civilians and the beheading of a Viet Cong soldier.
* "The Passion of the Christ" (2004): This film, based on the biblical account of the last days of Jesus Christ, features graphic depictions of violence, including the scourging, crucifixion, and resurrection of Jesus.
* "Cannibal Holocaust" (1980): This Italian exploitation film, set in the Amazon jungle, features graphic scenes of violence and cannibalism. It was banned in many countries due to its extreme content.
* "Salò, or the 120 Days of Sodom" (1975): This Italian drama film, set during World War II, depicts graphic scenes of torture, violence, and sexual depravity. It was also banned in many countries due to its extreme content.
