Demon Seed

Dr. Harris' futuristic-looking car was actually a production car, unmodified at the time of filming - a Bricklin SV-1. The Bricklin was built in Canada but intended for the U.S. market, featuring high performance and a number of innovative safety features (in fact, the model number stood for "Safety Vehicle 1"). The SV-1 was the only production vehicle in automotive history to have powered gull-wing doors that opened and closed at the touch of a button (on other gull-wing cars, like the DeLorean it's often compared to, the doors must be opened and closed manually). Fewer than 3,000 were produced during its short run from 1974-1976, and it's estimated that fewer than 1,120 remain in existence.

ICON's headquarters buildings were actually the City Hall for the city of Thousand Oaks, California. City Hall has since moved to a different location.

In the 1997 re-write of the novel "Demon Seed," author Dean Koontz has Alex Harris bestowing the name "Adam Two" upon his supercomputer/A.I. intelligence system. However, the computer dislikes that name, and chooses to associate itself instead with the Greek mythological figures, Prometheus and Proteus. It believes that its purpose is to bring advanced knowledge to humanity (as the mythical Prometheus introduced humans to fire,) but finally chooses its own name, Proteus, as an homage to an entity which can change at will, to become anything which it wishes to be.

The film was based on a very early novel by famed author Dean Koontz, published in 1973. "Demon Seed" was released to theaters in 1977. Much later, Koontz revised and updated the book, in a version released in 1997; it contains numerous technological updates and strong character differences from his original idea. As of 2016, Koontz' original novel version is not available either in print or in eBook formats.

Jerry Fielding's score to "Demon Seed" is included on the soundtrack to the film "Soylent Green (1973)" (which Fred Myrow composed).
