Logan's Run

1 9 7 6 (USA)

A good example of what passed for Sci-Fi before Star Wars was released and a real 1970s vision of the future.

A century after the apocalypse, a bunch of happy white people live inside the ultimate singles complex, a huge domed city that looks suspiciously like the Texas shopping mall it was filmed in.

Here they lounge around in skimpy disco clothing, do drugs, beam up sex partners on demand, and wait to turn thirty, which is when their hand crystal starts blinking red and they  get to float around in a cool zero-gravity area and blow up in front of a cheering crowd.

Logan's Run later became a silly TV series featuring Gregory Harrison from Trapper John MD.
