Korean filmmakers produced a movie called "Magu." In this 80-minute film, most of the content is conveyed through the naked body language of the actors, with only a small amount of poetic monologue interspersed. It is a work full of implications, aiming to warn humanity not to recklessly destroy our existing environment anymore. But when it was presented to the public, all attention was diverted from this so-called theme — the film shockingly features a group nudity scene involving 825 actors.
