In the not-too-distant future, the last two men on earth must adapt and evolve to save humanity, in veteran producer Mel Eslyn (THE ONE I LOVE)'s feature debut as director/co-writer (with Mark Duplass).

Billy (Mark Duplass) and Ray (Sterling K. Brown) are lifelong best friends, brothers from another mother – and the last two men on earth. Their survival is largely due to Ray, a brilliant scientist who designed a domed structure with all the systems necessary to sustain life on a planet that could no longer support it. Their custom biosphere is outfitted with basic necessities and creature comforts that make it possible to retain a sense of what life used to be like. A hydroponic garden provides fresh vegetables and a carefully managed fishpond supplies essential protein. Recently, however, fish have begun dying at an alarming rate. With a mere three fish remaining, Billy and Ray face an ominous future. But life may yet find a way.

press for Biosphere

"Like HUMPDAY, it’s an act of daring — we’re waiting for the movie to cop out because most movies do. This one doesn’t, and bravo for that."
- The Playlist
"Post-apocalyptic survival meets the anxious buddy humor of HUMPDAY in Biosphere, a mysterious and hilarious pic that really can’t be discussed much without saying things a prospective viewer would be better off not hearing."
- Hollywood Reporter
