Anyone recall the Disney Movie "Island At The Top Of The World" 1974 ??

It stared David Hartman (The guy who was also on Good Morning America) It takes me back to just me and my Dad going to see it at the theater a block and a half from the house I grew up in. It was the start of Christmas Break. I was in 2nd grade. I remember being totally fascinated by the blimp that had a Flying Tiger like mouth on it. It was a really cool movie for back in the day and a fond memory of time with my Dad.
