Gas, Or It Became Necessary to Destroy the World in Order to Save It (1970)

aka Gas-s-s-s

How bad is it? It's almost unendurable.
Should you see it? If you want to make fun of hippies.

With Bud Cort, Talia Shire, Ben Vereen, Cindy Williams and with appearances by Marshall McLuhan and Country Joe McDonald.

A gas leak causes the death of everyone over 25 years old and civilization is rebuilt, in a way, as re-imagined by youth. It was Roger Corman's last film for A.I.P. before going on to produce his own films, and he disowned it, saying that they ruined the ending, where people like Martin Luther King and Edgar Allan Poe rise from the dead and where apparently there was a scene of God's appearing that got cut. The film is largely people going from one scene to another, trying to be "hip." There's some fun to be had in making fun of the times and of the people trying to be something cooler than they were;it's also interesting to see future stars' early work.
