Finally!
After all these years, I've finally found this movie! Once in a while I'd remember this movie that I'd seen as a young boy: my mother had rented it or brought it home from the library one day (can't remember), and at first I thought it looked so "childish" and silly, but after watching it I remember thinking, 'boy - was I proven wrong!'
Great to finally find it after years of trying to do so on and off. :)
