Ray Harryhausen's animated creatures sparkled with predatory alertness and subtle quirks of behavior that stamped each with a distinct and memorable personality. His films are famous for being among the very best of the genre.

The first chapter of this book chronicles Harryhausen's formative years and work on numerous 16mm experiments, beginning with his viewing of King Kong in 1933. The next four chapters cover his four feature-length dinosaur films, The Beast from 20,000 Fathoms, The Animal World, One Million Years B.C. and The Valley of Gwangi, providing extensive information about all aspects of the staging of their stop-motion content and many additional facets of the overall production process. The paleontological accuracy of his saurians from a modern perspective is also examined. A chapter on his work and experiences in the 1970s and beyond discusses potential dinosaur projects, as well as The Golden Voyage of Sinbad.
