WARNING: This article contains SPOILERS for Opus.A24's musical horror film Opus presents a dark but unique tale about celebrities and the cults of personality they create. 2025's Opus follows a group of people invited to a legendary singer's recluse community of fans to hear his comeback album, only to learn some frightening truths about their beloved host and his fans. The film hits close to home with its depiction of Alfred Moretti and his religious cult of "Levelists," making it seem like Opus, which is getting mixed to negative reviews, is based on a true story.
