Universal Studios was the premiere source of horror films during Hollywood's golden age, producing Dracula, The Wolf Man, the Frankenstein movies, and many more films. For each of the 85 horror films made during this period, the authors provide a complete cast list with credits, a critical synopsis, and the production history, often with commentary by the cast or crew. Photographs are copious and well chosen. The authors' history is informal but very informative. When their judgments differ from the consensus, they ably defend their opinions. They are fans of the genre, but this does not blind them to the fact that many of the films in their book are dross. A broad definition of "horror" is used, so that many mystery films (including those with Sherlock Holmes) are included.
