The Outer Limits: Corpus Earthling (1963)

Parasitic advance guard from outer space strive to kill a physician, the only human who can hear them.

If you can accept  the premise that talking rocks are actually English-speaking alien invaders, then you might find this episode intriguing and well-played.

The Outer Limits: The Human Factor (1963)

At an isolated military installation in Greenland a scientist has invented a device that allows him to read the thoughts of another person.

A simple plot is set as a closed-room drama with only a few unconvincing effects and relies fully on the psychological aspects of the story.

The Outer Limits: O.B.I.T. (1963)

The Outer Band Individuated Teletracer, or O.B.I.T.,a remarkable technology that can track and monitor any individual, anywhere, for any length of time, until it comes under scrutiny, when a man is found dead, slumped over the machine.

Clairvoyant and gripping the plot's warning of future technologies may have been bleak at the time, but today the N.S.A. has surpassed its worst fears.

The Outer Limits: The Man Who Was Never Born (1963)

Earth awaits a terrible fate in the far future, so a 20th Century astronaut and a hideously malformed future Earthling go back in time hoping to change history.

A superb episode with some great acting (especially Martin Landau), a bunch of good scenes and sets and a gripping story with a downbeat twist ending.

The Outer Limits: The Sixth Finger (1963)

A scientist experimenting with speeding up human evolution, hires on uneducated, but bright young man, from the nearby Welsh mining town.

Scientifically probably a bad idea, but David McCallum's metamorphosis into a weird superior being of the future is  quite entertaining.

A milquetoast college teacher Harold gets a brain operation so he can aide in a space project to mine asteroids, and a giant electrical vortex appears when he's angry at someone, unleashing the earth's Magnetic Fields against the offender.

Mediocre episode redeemed by Donald Pleasance's excellent performance.

The Outer Limits: The Architects of Fear (1963)

A secret group of scientists decide to surgically alter one of their members into an 'alien', in order to convince the world that an alien invasion is imminent.

The premise is quite outlandish and the monster is incredibly silly, but the episode is well made and has some good acting.

The Outer Limits: The Hundred Days of the Dragon (1963)

A sinister foreign power replaces the President of the United States with its own agent via the use of a powerful drug allowing the skin to be molded into any likeness.

Mesmerizing plot in the vein of The Manchurian Candidate is suspenseful and has some great Noir atmosphere, but the happy ending is rather disappointing.

The Outer Limits: The Galaxy Being (1963)

Adventurous radio station operator contacts a fellow experimenter in another galaxy.

First episode of the cult series sets the mark for the concept: imaginative story executed with good direction, appropriate performances and state-of-the art (and now dated) special effects.
