Project X is a 1968 independently made color science fiction film, produced and directed by William Castle, starring Christopher George, Greta Baldwin, Henry Jones, and Monte Markham.

The film was distributed by Paramount Pictures and is adapted from the science fiction novels The Artificial Man (1965) and Psychogeist (1966) by L. P. Davies.

Project X's story echoes some geopolitical themes of the late 1960s, such as overpopulation, emerging genetic engineering, biological warfare, cryogenics and fear of Asian dominance.

It mixes in science fiction concepts like holographic devices, memory manipulation and viewing, and virtual environments to create a story about futuristic espionage.

As the days tick down until the East destroys the West, Hagen comes into contact with a futuristic factory worker named Karen Summers who causes slight anachronistic errors with the 1960s facade.

[citation needed] Another reuses a previous shot from the animated Jonny Quest TV series of an underwater elevator which terminates inside a submarine on the ocean floor.

All animated and some live action sequences were further enhanced with either visual haze, wavy imagery, double exposures, reverse-negative images, monochromatic colors, and other optical effects available in the era.
