Mozart's opera 'The Magic Flute' is a perfect point of entry for kids. There's plenty of fantasy, a happy ending, no one dies and the music is sublime. But for director Tomer Zvulun, it's all about the magic. "I was a really weird kid," he says. "My obsession was film, and I was into (Ingmar) Bergman, (Federico) Fellini and (Alfred) Hitchcock. I was 16 when I saw Bergman's film of 'The Magic Flute,' and suddenly it all made sense." Cincinnati Opera offers its production Wednesday, Friday and Sunday at Music Hall.
