John Carpenter

(S03E12) There's no way that Kripke and the team over at Supernatural HQ could have foreseen the strike, only completing 12 episodes, and an extended break after episode 12. Had they been able to do that though, it's hard to imagine a better send off as we head into the break than what we saw in "Jus In Bello." The return of Henricksen and the introduction of Lilith made for a great mid (3/4) season intermission.

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.
