'Brother Joseph and the Grotto' tells the 'true fairy tale' of Brother Joseph, the tiny Bavarian hunchback monk who built Ave Maria Grotto, a miniature city of recycled materials in the Alabama woods. Brother Joseph had a stepmother, took a long journey, got a new name, conducted a superhuman feat, lived in the woods, was 'protected' by a godmother, and more -- all features of classic fairy tales, which is why this documentary is framed as one and constructed of interviews, re-enactments, voluminous archival footage and storybook illustrations.
