Great film. The special effects I think won an Academy Award for George Pal ( if not he was nominated for one).

Frank Cady  (Mr. Drucker from Green Acres) appeared as John Hoyt's butler. Also Hayden Rourke from I Dream Of Jeannie appeared as one of the scientists.

The final scene when they land on the new planet was beautiful but looked unrealistic.
But still a great sci fi film from the 50's.
