now this is a movie I don't think I ever saw until the 1990s on TNT, back when it played good stuff. it's so much fun and even with Phyllis Diller it's got awesome voice talent. the musical score is pretty wonderful as well.
I did see the pseudo-sequel on the ABC Saturday Morning Movie "Mad Mad Mad Monsters" and I have fond memories of that. it's not quite as good, but still a lot of fun.
