This 35mm screening is part of the John Carpenter season at BFI Southbank. Carpenter's film got a fairly lukewarm response on release but has increasingly garnered a fan base and is well worth tracking down. This article on They Live by Jonathan Lethem at salon.com is fascinating but be warned: here be spoilers.
Chicago Reader review:
John Carpenter's 1988 SF action-thriller about aliens taking over the earth through the hypnotic use of TV. The explicit anti-Reagan satire—the aliens are developers who regard human beings as cattle, aided by yuppies who are all too willing to cooperate for business reasons—is strangely undercut and confused by a xenophobic treatment of the aliens that also makes them virtual stand-ins for the Vietcong. Carpenter's wit and storytelling craft make this fun and watchable, although the script takes a number of unfortunate shortcuts, and the possibilities inherent in the movie's central conceit are explored only cursorily. All in all, an entertaining (if ideologically incoherent) response to the valorization of greed in our midst, with lots of Rambo-esque violence thrown in, as well as an unusually protracted slugfest between ex-wrestler Roddy Piper and costar Keith David.
