Universal spent money on a technicolor science fiction film called This Island Earth, and is it ever in technicolor the sets practically jump out with all the bright glossy colors. The story involves aliens from the planet Metaluna capturing our nuclear scientists for their own nefarious purposes. In this case creating nuclear energy to help in their war with another planet called Zagon.
Understandably the special effects for 1955 don't seem so special any more and the big monster called a "mutant" lumbers around so slowly that it's hard to believe it could catch or scare anyone. Still the film is entertaining and doesn't wear out it's welcome running only 86 minutes.
The film is sort of a 1950's science fiction film classic and was written by Franklin Coen and Edward G. O'Callaghan.
Interestingly enough William Alland the producer had appeared in Citizen Kane as the reporter Thompson, trying to solve the mystery of "Rosebud."
