Omicron (1964)

During a walk, two young brothers and their babysitter find the body of a worker, Trabucco, wedged inside a concrete pipe. Everyone believes he is dead. In fact, he is possessed by Omicron, an ethereal being from the planet Ultra, whose inhabitants want to take over Earth. Before Trabucco-Omicron can be subjected to an autopsy, he manages to make the body containing him function. But he cannot decipher human language because he has not yet managed to awaken human knowledge. Meanwhile, thanks to his body’s extraordinary new mechanical abilities, he is rehired at the factory where he used to work. He gets up to all kinds of mischief and tries to assault Lucia, a worker in the company cafeteria. He then discovers the place where the workers planning to go on strike meet and unwittingly betrays them. When he realizes that he loves Lucia and begins to regain consciousness, Omicron would like to return to his planet, but he cannot do so until Trabucco is killed while urging the workers to strike. By now, the invasion of the world has begun.
