Category III refers to a classification used primarily in the context of films, particularly in Hong Kong cinema. This category is designated for movies that contain explicit sexual content, graphic violence, or other adult themes, making them suitable only for mature audiences. Films in Category III often push the boundaries of conventional storytelling, exploring taboo subjects and challenging societal norms. While they may attract controversy, these films can also gain a cult following and are sometimes recognized for their artistic merit or unique perspectives on complex issues.
