I remember seeing this movie with my brother at the theater back in 1971. When we arrived, we received a book with the language used in the movie and a rough translation. I can find no mention of that book on any web site, and haven't purchased the video to see if it is still printed. It was great fun watching it again today after so many years. Even without the translation, the movie is very enjoyable and great fun to watch. Although the "dinosaurs" leave a little to be desired compared to today's movies, they did a great job integrating real lizards into the film.
