Query: Excellent book for reference or just entertainment

I host a movie show in Cleveland and am constantly on the search for good reference materials, and when I saw this book I knew it was one I wanted. When it came I was absolutely amazed at not only the scope of the book but by the quality of the writing and information in it. Bill Warren has written a highly readable and incredibly informative book and I recommend it to anyone who's into Sci-Fi movies of the fifties. Absolutely invaluable.
