Invisible Invaders

Dr. Karol Noymann (Carradine), an atomic scientist, is killed in a laboratory explosion. His colleague, Dr. Adam Penner (Tonge), is disturbed by the accident and resigns his position and calls for changes.

At Dr. Noymann's funeral, an invisible alien takes over Noymann's dead body. The alien, in Noymann's body, visits Dr. Penner and tells him the Earth must surrender or an alien force will invade and take over the Earth by inhabiting the dead and causing chaos. The alien demonstrates to Penner that they are able to make things invisible. Penner tells his daughter Phyllis (Byron) and Dr. John Lamont (Robert Hutton) about the experience and asks Dr. Lamont to relay the message to the government in Washington, D.C.. The government ignores the warning and Dr. Penner is labeled a crank by the media.

Dr. Penner takes his daughter and Dr. Lamont to Dr. Noymann's grave, where they are visited by an invisible alien. Later, at the site of a plane crash, another alien takes over the body of a dead pilot (Don Kennedy), goes to a hockey game, chokes the announcer, and issues an ultimatum for the Earth to surrender. Another alien takes over a dead body from a car crash and issues the same ultimatum at a different sporting event. The media announce the threat and the governments of the world decide to resist the invasion. Aliens take over more dead bodies and blow up dams, cause fires and destroy buildings.

Maj. Bruce Jay (Agar) arrives to take Dr. Penner, Phyllis and Dr. Lamont to a secret bunker. On the way, they are confronted by a scared farmer (Hal Torey) who tries to take their vehicle. Maj. Jay kills the farmer and they proceed to the bunker while an alien takes over the dead farmer's body.

At the bunker, they are contacted by the government and tasked with stopping the alien invasion. They determine that the aliens are radioactive, and decide to capture an alien to conduct tests on. They attempt to spray an alien with acrylic to seal it in plastic, but this fails. They then fill a hole with the acrylic liquid and lure an alien into it. Once captured, the alien is taken to the bunker.

Back at the bunker, they confine the alien in a pressure chamber and break the acrylic using high pressure to set it free. They try several experiments, but nothing affects the alien. Frustrated and hopeless, Dr. Lamont wants to surrender, but Maj. Jay does not. The two men fight and inadvertently damage some electronic equipment, setting off a loud alarm. They notice that the alien reacts violently to the noise.

They make a sound gun and test it on the alien, causing it to become visible and killing it in the process. They try to inform the government, but their radio broadcast is jammed by the aliens, who are apparently nearby. Using a radio direction finder they follow the jamming signal to the alien ship, killing several aliens along the way. Maj. Jay walks through the woods to get to the ship and is confronted by several aliens. He kills them with the sound gun but is shot in the process. Despite being wounded, he finds the alien ship and shoots it with the sound gun, causing the ship to explode. With the jamming signal silenced, Dr. Penner is then able to contact the government and tell them how to stop the aliens while Phyllis tends to Maj. Jay's wound.

Later, at the United Nations, Dr. Penner, Dr. Lamont, Phyllis Penner and Maj. Jay receive thanks for saving the world from the alien invasion.

Production of Invisible Invaders began in December 1958.[2] The film was made as part of a package deal with The Four Skulls of Jonathan Drake. It was the fourth science fiction film made by Premium Pictures.[3]

The shooting schedule and budget are not known. Byron said in an interview that the "picture was filmed rather quickly. I remember the director moving from one set-up to the next very rapidly".[4] Film critic Bill Warren called it a "cheap little picture", noting that it "couldn't possibly have had a shooting schedule longer than two weeks (probably one)" and that the movie gives "every evidence of having been made in great haste".[5]

Costs were held down, in part, by re-use of special effects artist Paul Blaisdell's monster costume from 1958's It! The Terror from Beyond Space (also directed by Cahn)[6] during a sequence in which one of the invaders is encased in plastic so it can be seen. According to author Randy Palmer, "To help camouflage the costume, optical effects were added to lighten the image and give it a distinct blur, so that it's very difficult to tell that the invader's true form matches that of (Blaisdell's) Martian Lizard Man".[7] However, as Warren pointed out, by 1959 "no one cared about SF movies made on this budget level. They were just a product to get on the screen as soon as possible".[5]

Warren also commented on the film's extensive use of stock footage. "A great flurry of stock shots" were used "as the invaders smash things all over the world - fires, quakes, buildings collapsing, dams bursting". This is "dispiriting," but "the very cheap and shoddy effects match the overall tone" of the movie. The stock footage includes the fatal car wreck scene from 1958's Thunder Road.[5] Footage shot for the film itself was also repeated, with scenes re-used of the invisible alien making parallel grooves in the dirt as it shuffles toward Dr. Noymann's grave and then pushes aside some bushes.[5]

Invisible Invaders was released to US theaters on May 15, 1959.[2] It was copyrighted on 8 May that year,[8] a week before the film opened. Outside the US, it opened in Finland on August 12, 1960 and in Sweden on September 22, 1960. It was also exhibited in theaters in Brazil, Chile, Spain and the Soviet Union.[9] In the UK, it received an "A" certificate from the British Board of Film Censors on June 15, 1959,[10] which allowed it to be shown to "children accompanied by anyone over 16".[11]

To drum up domestic interest in the film, Variety said in its "Exploitips" listing that "the attention-getting title is the chief selling point - a ballyhoo man dressed in a rented space suit ... will get notice from neighborhood youngsters".[12] Whether this was actually done, or if it convinced children to attend the movie, is unknown.

In a review of the Blu-ray release of Invisible Invaders, Christopher P. Jacobs noted that in an audio commentary, noted sci-fi author Dr. Robert J. Kiss "gives some interesting data on the film's 1959 release and exhibition history, noting how it was almost always shown as the second of a double feature, quickly shifting from one-week runs to bookings of only a couple of days".[13] However, the movie wasn't always the second feature. According to a contemporary advertisement for the New Plaza Theater in Odessa, Texas, Invisible Invaders was the third movie on a triple feature, with Plan 9 from Outer Space as the first movie and The Snorkel as the second, showing on September 27 and 28, 1959, just four months after Invisible Invaders was released.[14]

The movie had only a short run but became a minor cult film on television.[15] Jacobs says it had "unprecedented success in 1962 prime-time TV showings, after low ratings as a late night movie".[16] For example, Invisible Invaders was shown on Chicago's WFLD in 1971 as part of its well-known "Science Fiction Theater" program.[17] TCM ran the film as part of a monster movie marathon on New Year's Day 2007.[18]

Paul Dunlap composed the music for Invisible Invaders. Dunlap would later use much of the same music in three other science fiction movies: The Angry Red Planet later in 1959, The Three Stooges in Orbit in 1962, and Destination Inner Space in 1966.
