I'll never forget watching this film at the ripe old age of 10 at the local drive in with my grandma and aunt. This was my favorite author with his own really cool movie. Boy that was a long time ago. I have a VHS tape of this film, and would like to buy a DVD of it, but the quality of all the DVD's I seen are no better than the tape I do have.
It was a masterpiece of animation/live action created in a format called "Mystimation". The look of this film was intended to be in the same idea as the pen and ink drawings that were present in some versions of Vern's works. I loved it, and I watch it from time to time for the fond memories of a time when your imagination was the special effects of the day. Films the like of this one are gone forever and will never return. The story told by the film isn't as important as the time and place it was viewed. I hope all you Scifi movie folks get to see this treasure at least once.
