This Island Earth (1955)


This Island Earth is a 1955 American science fiction film from Universal-International, produced by William Alland, directed by Joseph M. Newman and Jack Arnold, that stars Jeff Morrow, Faith Domergue and Rex Reason.

It is based on the eponymous 1952 novel by Raymond F. Jones, which was originally published in the magazine Thrilling Wonder Stories as three related novelettes: “The Alien Machine” in the June 1949 issue, “The Shroud of Secrecy” in December 1949, and “The Greater Conflict” in February 1950.


Dr. Cal Meacham is flying to his laboratory in a borrowed Lockheed T-33 Shooting Star jet. Just before landing, the jet’s engine fails, but he is saved from crashing by a mysterious green glow.

At the lab is an unusual substitute for the electronic condensers that he had ordered. Instead, he discovers instructions and parts to build a complex device called an “interocitor”. Neither Meacham nor his assistant Joe Wilson have heard of such a device, but they immediately begin its construction. When they finish, a mysterious man named Exeter appears on the interocitor screen and informs Meacham that he has passed the test. His ability to build the interocitor demonstrates that he is gifted enough to be part of Exeter’s special research project.

Intrigued, Meacham is picked up at the airport by an unmanned, computer-controlled Douglas C-47 aircraft with no windows. Landing in a remote area of Georgia, he finds an international group of top scientists already present, including an old flame, Dr. Ruth Adams. Cal is confused by Ruth’s failure to recognise him and suspicious of Exeter, his assistant Brack and other odd-looking men leading the project.

Cal and Ruth flee with a third scientist, Steve Carlson, but their car is attacked and Carlson is killed. When they take off in a Stinson 108 light aircraft, Cal and Ruth watch as the facility and all its inhabitants are incinerated. Their aircraft is then drawn up by a bright beam into a flying saucer. Exeter explains that he and his men are from the planet Metaluna and are locked in a war with the Zagons. They defend against the Zagons with an energy field, but are running out of uranium to keep it running. They enlisted the humans in an effort to transmute lead to uranium, but time has run out. Exeter takes the Earthlings back to his world, sealing them in protective tubes to offset pressure differences between planets.

They land safely on Metaluna, but the planet is under attack by Zagon starships guiding meteors as weapons against them. The defensive “ionisation layer” is failing, and the battle is entering its final stage. Metaluna’s leader, the Monitor, reveals that the Metalunans intend to flee to Earth, then insists that Meacham and Adams be subjected to a Thought Transference Chamber in order to subjugate their free will, which he indicates will be the fate of the rest of humanity as well upon Metalunan relocation. Exeter believes that this is immoral and misguided.

Before the couple can be sent into the brain-reprogramming device, Exeter helps them escape. Exeter is badly injured by a Mutant while he, Cal and Ruth flee from Metaluna in the saucer, while the planet’s ionisation layer becomes totally ineffective. Under the Zagon bombardment, Metaluna heats up and turns into a lifeless “radioactive sun”. The Mutant has also boarded the saucer and attacks Ruth, but dies as a result of pressure differences on the journey back to Earth.

As they enter Earth’s atmosphere, Exeter sends Cal and Ruth on their way in their aircraft, declining an invitation to join them. Exeter is dying, and the ship’s energy is nearly depleted. The saucer flies out over the ocean and rapidly accelerates until it is enclosed in a fireball, crashes into the water and explodes.

Principal photography for This Island Earth took place from 30 January to 22 March 1954. Location work took place at Mt. Wilson, California. Most of the Metaluna sequence was directed by Jack Arnold; the front office was apparently dissatisfied with the footage Newman shot and had it redone by Arnold, who unlike Newman had several sci-fiction films to his credit.

Most of the sound effects, the ship, the interociter, etc. are simply recordings of radio teletype transmissions picked up on a short-wave radio played at various speeds. In a magazine article, the special effects department admitted that the “mutant” costume originally had legs that matched the upper body, but they had so much trouble making the legs look and work properly that they were forced by studio deadline to simply have the mutant wear a pair of trousers. Posters of the movie show the mutant as it was supposed to appear.

This title was one of the very few flat widescreen (FWS) titles to be printed direct-to-matrix by Technicolor. This specially ordered 35-millimetre printing process was intended to maintain the highest possible print quality, as well as protect the negative. Another film that was also given the direct-to-matrix treatment was Written on the Wind, which was also a Universal-International film.


This Island Earth was released in June 1955, and by the end of that year had accrued US$1,700,000 in distributors’ domestic (US and Canada) rentals, making it the year’s 74th biggest earner.
