Perhaps. A few sites, citing an Empire Magazine interview with They Live star Roddy Piper, report that Carpenter was in talks with SciFi to develop his 1988 film into a TV series for the network.

Unfortunately, that's all we know, and it doesn't look as if the interview is on Empire's Web site. Nevertheless, I think this could be a really cool idea. They Live was a lot of fun in a campy, B-style sort of way, and its not-so-subtle plot of aliens trying to control mankind through subliminal methods is something that could be easily fleshed out into a full series. In the film, Piper's character, John Nada, finds a pair of sunglasses that allow him to see the various subliminal messages broadcast across the city: OBEY, CONSUME, etc.
