I remember seeing this in a the Salem movie theater (where I used to attend "Kiddie Matinée"s almost every Saturday) in Dayton, Ohio when I was a young boy and have never forgotten it. It simply amazed me and my friends. I do wish there were some way I could see it again! I have tried to find some compilation of shorts or something like that to no avail. I only recently discovered that it was a Cousteau film and that blew my mind even more. How the heck he accomplished this is beyond my understanding. The fish is ACTUALLY IN THE CAT'S MOUTH at one point, if I remember correctly! If anyone could help me find a way to see it again I would be extremely grateful!
