->''"I will return to my planet Arous, and through its vast intellect, I will become master of the universe. After I'm gone, your earth will be free to live out its miserable span of existence, as one of my satellites, and that's how it's going to be."''
-->-- '''Gor''', finishing his ultimatum to national representatives

A scifi BMovie from 1957, directed by Nathan Juran (credited as Nathan Hertz).

An alien spacecraft lands inside a mountain in Nevada desert, and two nuclear scientists, Steve and Dan, go to investigate the radiation its causing. They come across an alien brain named Gor, who [[SharingABody takes over Steve's body]] and kills Dan, and sets out to attain his goal of conquering Earth, and then the universe. Following on Gor's (nonexistent) heels, another alien brain named Vol arrives to help the locals to stop him.
