The official trailer for Biosphere starring Sterling K. Brown and Mark Duplass is here.

Biosphere is set “in the not-too-distant future” as “the last two men on earth must adapt and evolve to save humanity.

Here’s an official description:

Billy (Mark Duplass) and Ray (Sterling K. Brown) are lifelong best friends, 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 fishpond—which supplies essential protein—begins waning, the men find themselves facing an ominous future. But life may yet find a way… 

'Biosphere' is the directorial debut of producer Mel Eslyn and is produced by Duplass Brothers Productions.

Mark Duplass co-wrote, stars, and serves as executive producer. Biosphere is produced by Zackary Drucker, Eslyn, Maddie Buis and Shuli Harel.

“I think for me, my personal manifestation and desire is to love without limits,” Sterling K. Brown said when talking about the film at its TIFF World Premiere at the Princess of Wales theater in 2022. “I come from a very conservative place in St. Louis, Missouri where growing up in the ’80s, homophobia is sort of the default way of being, even to the point where you don’t realize you’re being homophobic when using certain words. I think I’ve been blessed enough in this path [that] I’ve chosen to be taken out of where I grew up and recognizing humanity in many forms. I believe this film’s message is important because so many people still think that humanity can only be recognized in very particular forms that they are familiar with.”
