**SPOILERS** The only thing new about this aliens from space movie is that the aliens, or as their called in the film parasites, don't come from other space at all they come from deep down in the earths core.
It take's a while for Dr. Paul Kettering, Ed Nelson, and the person put in charge of this pressing matter by the US Department of the Interior Senator Warren K. Powers, Cornelius Keefe,to realize what exactly their up against. These strange brain-eating creatures are in fact 200 million year old amoeba-like brain-suckers who emerged from their home deep down in the earth's crust. The creatures are planning to take over the human race by destroying their victim's brain cells after they took over their bodies. They, the Braineaters, plan to accomplish this feat by first taking over the brains of the unsuspecting humans in the little town of Riverdale. Turning the town's population into mindless zombies the parasites then plan go on to the next town city and then country until the entire human race is no longer a factor or obstacle to their eventual conquest of the earth!
With little money on hand the film "The Braineaters" lacks the very things that would make it worth watching decent, not spectacular , special effects. The "spaceship" that the parasites came from is nothing but a 50 feet tall aluminum tepee with a hole in it's nosecone. The Braineaters themselves are nothing but sponge-like creatures with pipes sticking out of them. These pipes are used to latch on to their victim's necks and then, after taking over their bodies, suck their brains out and cause their victims to die within 24 to 48 hours.
It's after the town chief executive Mayor Cameron, Oville Sherman, flips out and goes bananas and is shot and killed by the police, whom he's in charge off,that Dr. Kettering realized that he was in fact taken over by some strange creature, the underground parasite, who had him do its bidding. Little by little the parasites take over a number of the townspeople including Dr. Kettering's girlfriend Alice Summers, Joanna Lee, making it almost impossible to know who's the good guy or parasite.
It's only when it's discovered that there's a number of persons inside the "spacecraft" that the truth comes out to what exactly is going on. One of the men inside the craft turned out to be Prof. Helsingman, Saul Bronson, who mysteriously disappeared five years ago. Helsingman lived just long enough to tell Dr. Kettering what the real purpose of these strange creatures really is: To take over the earth's surface.
Later going into the craft Dr. Kettering is confronted by the also long missing Dr. Cole, Leonard Nimoy, the late Prof. Helsingman's close friend and associate. Dr. Cole, looking like the old man of the mountain,tells the astonished Dr. Kettering that he and his fellow humans should just lay down their arms and give up, resistance is futile Dr. Cole tells him, to their superiors the parasites.
Of course Dr. Kettering is not at all impressed with Dr. Cole and his army of brain eating parasites and comes up with a fool-proof plan to put them out of business: 60 to 80 thousand volts of electricity. It , Dr. Kettering's plan, was just about to be put into operation when an unexpected glitz developed at the very last moment! The sudden appearance of of girlfriend the brain damaged, and parasite controlled, Alice Summers!
Predictable ending with Dr. Kettering unable to do what he at first planned to do in ridding the earth of the underground parasite invasion. It took the sharp-shooting ability of the late Mayor Cameron's son Glenn, Alan Frost, to in the end finish the job that the reluctant, in not being able to off his parasite-controlled girlfriend Alice, Dr. Kettering was unable to do.
