Boy Kills World (2023) is a hyper-violent action revenge film set in a stylized dystopian society. Starring Bill Skarsgård as a deaf-mute assassin driven by vengeance, the film blends martial arts combat, comic-book brutality, and dark humor. Its exaggerated violence and video game–like structure place it firmly within modern exploitation-influenced action cinema.
