SPOILER: For the American release, titled "Voyage to the End of the Universe," American International Pictures cut the film up, changing a number of things:
- Approximately 26 minutes of footage were removed (including a sequence in a man-made flying saucer carrying dead capitalists, nerve gas and an atomic bomb).
- The story was changed substantially, the ship's flight direction reversed (making it an alien ship traveling to Earth), and the Statue of Liberty pasted into the final shot.
- The cast and staff's names in the credits were altered significantly to look like English.
