Kubrick’s anti-war film “All-Metal Shell” describes the psychological process of a soldier in different stages of the war in the context of the Vietnam War. But all the scenes of the film were filmed in England.
In the film, American soldiers blew up a small Vietnamese town, which was actually taken at an abandoned gas plant in London. Originally, Kubrick wanted to blow up the gas plant directly, but was interfered by the British military. Therefore, he could only set up a detonation point in the building and smash the wall with a hammer, resulting in a very fierce war.
Of course, because Kubrick is pursuing a perfect personality, as usual, he asked the actor to perform in this scene countless times before passing.
