I first saw this movie when I was about 12 or 13 years old. It's incredibly cool. However, I think IMDb got it wrong- I believe the movie consists of 5 episodes of Johnny Sokko and his Flying Robot, not 4. The episodes in the movie are as follows:
Episode 1 - Dracolon - The Great Sea Monster.
Episode 2 - Nucleon - The Magic Globe.
Episode 10 - The Transformed Humans.
Episode 17 - Destroy the Dam.
Episode 26 - The Last of Emperor Guillotine.
All of the Johnny Sokko episodes are available to watch on Hulu. So if you want to re-live Voyage Into Space, watch the above-listed episodes.
