Demon Seed (1977)
“Tonight, I’ll impregnate you. In 28 days you’ll give birth to a child.” These words don’t come until almost an hour into Demon Seed, a 1977 horror film starring Julie Christie, but it’s what the viewer has been waiting for. With a title like that—and design art in which the “o” in Demon is altered to not-so-subtly suggest a vagina—the movie telegraphs where it’s going with the light touch of a Howitzer.
Story-wise, Demon Seed is a trashy shocker from the wheelhouse of Dean Koontz, the poor man’s Stephen King. It opens with an explanation of Proteus IV, an artificial intelligence program which will—it’s explained, in the kind of unintentionally comical line that doubles nicely as a meta-commentary on the film—“make obsolete many of the functions of the human brain.” After being turned down in its request to study humans, Proteus secretly takes over a terminal in the basement of scientist Alex Harris; the rest of the home is occupied by his soon-to-be-ex-wife, Susan (Christie). The house is equipped with the latest in what passed for futuristic technological gadgetry in late ’70s cinema, with everything from the coffeemaker to the locks controlled by a voice-activated computer program. Proteus immediately takes over and imprisons Susan in her own home, a situation—as with most things in life nowadays—that was ably parodied by The Simpsons.
But where The Simpsons’ Pierce Brosnan-voiced program falls in love with Marge, Proteus’ interest in Susan essentially begins and ends with her womb. Proteus may be the sum total of knowledge on Earth, programmed to be ultimately reasonable, but it still wants to feel the sun on its face. Held prisoner in her own home, Susan has to decide whether to consent to the procedure and permit this man-machine birth operation to proceed, or have her mind wiped and the process done anyway.
