A new documentary about the bizarre Biosphere 2 "human zoo"

Built in the late 1980s, Biosphere 2 is the human habitat in Oracle, Arizona that was meant to help scientists understand how humans might live in space. In 1991, eight people went inside for two years of experimental quarantine inside the vivarium. The premise, and much of what happened, would make for a great JG Ballard novel. Spaceship Earth, a new documentary about Biosphere 2 directed by Matt Wolf, promises to tell the real tale, warts and all. It premieres online May 8. From Neon, the indie studio releasing the film:

The [Biosphere 2] experiment was a worldwide phenomenon, chronicling daily existence in the face of life threatening ecological disaster and a growing criticism that it was nothing more than a cult. The bizarre story is both a cautionary tale and a hopeful lesson of how a small group of dreamers can potentially reimagine a new world.
