Marshall Thompson plays a naval officer whose brother, a hot shot test pilot, manages to get about 250 miles above the earth. Said brother then returns looking like something that crawled out of the La Brea Tar Pits. This creature goes on a rampage, seeking blood from humans and cows. It returns to its senses, somewhat, at the finale, and explains what happened in space.

But getting to the finale is a chore, because there is mostly talk, and too many people acting unwisely. For example, the creature breaks into a blood bank at night, tears off a door, and creates a lot of noise. A nurse goes to investigate, and walks calmly past the smashed-in door, without bothering to get help first. Some people deserve to have their blood drained.

Supposedly set in New Mexico, the mostly British cast do a decent job disguising their accents, but their uniforms and spelling ("authorised") give them away.

An astronaut , Navy test pilot Lieut. Dan Prescott -Bill Edwards-, in experimental rocket plane Y-13, disobeys orders and becomes the first man to fly outside the ionosphere. When he returns to Earth by ejection he is covered with strange space dust and having a craving for blood . While his brother, an Air Force commandant, -Marshal Thompson- attempts to look for the missing astronaut throughout the countryside along with his girlfriend : Maria Landi . The pilot compartment lands with no trace of the pilot... but first animals , then people, are found their members cut . It leaps out the head lines !.Far and away the most startling and unexpected adventure film ever made!

A monster/sci-fi movie with special effects-laden and a lot ot stock-footage, dealing with an astronaut falling on Earth , being plastered with metallic meteor dust and with a starving organism needing to feed , along the way an alien tries to survive and begins killing in order to get it . First picture to lift the veil in an unpredictable future , concerning a spectacular drama of the first man in history to be rocketed into the terrifying unknown of outer space . On the virtues of this low-budget movie results in an original and eerie story with suspense , tension and horror . In spite of its short budget , filmmaker Robert Day uses his imagination indeed , that's why so often directors make their best movies when they don't have that much money. Passable FX and make-up , as the creepy astronaut/monster suit was so heavily made and risked thermal , it could only be worn for a few minutes at a time .

It contains a peculiar score , using electronic music by Buxton Orr. As well as atmospheric Cinematography in black and white by Geoffrey Faithfull .The motion picture was uneven but professionally directed by Robert Day. His first film as director, the black-comic The Green Man (1956) for the writer-producer team of 'Frank Launder and Sidney Gilliat´, garnered fine reviews and a classic notoriety ; using this as a starting point , Day went on to become one of the industry's busiest directors . He relocated to Hollywood in the 1960s and began directing scads of TV episodes and made-for-TV movies on this side of the Atlantic. He occasionally turns up in bits in his own productions , including Grip of the Strangler (1958), Two way stretch (1960), the mini-series Peter and Paul (1981) . Robert was a craftsman who directed all kinds of genres as Tarzan movies : Tarzan's three challenges, Tarzan and the great river , Tarzan and the valley of gold , Comedy : Two way stretch , Terror : Corridors of blood , Thriller : Operation snatch . And he made a lot of episodes of TV series as Perry Mason, Kingston confidential, McCloud , Logan run , Robin Hood, Kojak, Sam Cade, Ironside, Streets of San Francisco, Dallas, Disneyland, among others. Rating : 5.5/10 . Fair Sciencie Fiction/monster/terror movie that will appeal to the usual aficionados .

A not too exceptional fifties science fiction film involves an impulsive astronaut who can't follow orders. The up side is that it has allowed the program to go ahead by leaps and bounds; the down side is that he is out of control. On a dangerous mission, he breaks through the earth's atmosphere and finds himself in orbit. While there, he passes through some space dust which coats his ship and him. The ship comes down, an automatic parachute breaking the fall (sort of hard to swallow) and when it is found, Dan is gone. We finally get to see him. He is in a monster suit that is impenetrable (actually it's his skin). He also has a lust for as many pint of bloods as he can get his hands on. He goes on a killing rampage. Hs brother, who warned him about his lack of coach-ability (spoilsport), is trying to save him while other work to do him in. He ransacks a blood bank and siphons several innocent people. The movie shots of space are better done than most, but the acting is stiff and uninspiring, with dull sets and little real action.
