Film / The Brain from Planet Arous

"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 representativies

A scifi B-Movie from 1957.

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 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, an another alien brain named Vol arrives to help the locals to stop him.

This film has examples of:

  • Achilles' Heel: The very top of Gor is the only place that can be damaged. After learning this from Vol, Sally hides a message about it to Steve to give him a chance to defeat his possessor.
  • Black Eyes of Crazy: When Gor uses his powers of radiation through his vessel Steve, his eyes become black.
  • Brain Monster: Gor and Vol are aliens that resemble giant disembodied floating brains. The former wants to take over the universe, the latter wants to stop him.
  • Evil Gloating: After reading Sally's message on Gor's weak spot, Steve manages to kill him with a nearby axe after he leaves his body to do some Evil Gloating.
  • Evil Laugh: Gor, through Steve, is very gleeful in his evil proceedings, and usually caps them off with an evil laugh.
  • Mars Needs Women: Justified, Gor, possessing Steve's body, wants to get horizontal with his host's fiancée because he wants to indulge all the possible senses; being a disembodied brain, having any sensation at all is a novelty.
  • My Brain Is Big: Both Gor and Vol are giant, disembodied floating brains.
  • Not Right in the Bed: Possessed Steve's new forceful courting of Sally puts her off even before she learns that he is a vessel for an alien.
  • Title Drop: Sally tells Steve that Vol is an another "brain from planet Arous".
