There are plenty of movies about the last people on Earth, but – based on the first trailer – Biosphere could be among the most charming. Mel Eslyn’s first film, Biosphere stars Sterling K. Brown and Mark Duplass as humanity’s sole survivors, who also happen to be best friends living together inside the titular biosphere. It looks very comfortable. They even play video games.

Things are going well until, well, I let the official synopsis do the work:

In the not too distant future, Billy (Duplass) and Ray (Brown) are best friends forever, brothers from another mother, they also happen to be the last two men on earth. Their survival is largely due to Ray, a brilliant scientist who designed the custom biosphere they call home, outfitting it with both creature comforts and the necessities to sustain life on a doomed planet. When the population of their fish pond – which provides essential protein – begins to decline, the men face an ominous future. But life can still find a way…

Biosphere made its debut at TIFF last yearand it will finally get a wider theatrical release and on-demand services on July 7th.
