Biosphere (2022) Ending Explained
TL;DR:
Biosphere (2022) is a sci-fi comedy-drama directed by Mel Eslyn, starring Mark Duplass and Sterling K. Brown as the last two men on Earth, living in a sealed biosphere after an apocalyptic event. The film explores themes of survival, masculinity, and evolution through their bizarre and often humorous dynamic. The ending reveals that the duo's isolation triggers a biological transformation in one of them, symbolizing humanity's need to adapt for survival. The film concludes ambiguously, leaving their ultimate fate open to interpretation while emphasizing themes of change, acceptance, and the fluidity of identity.
Detailed Ending Explanation
The ending of Biosphere is a surreal and thought-provoking culmination of the film's themes. After spending the entire runtime in the confined space of the biosphere, Billy (Mark Duplass) and Ray (Sterling K. Brown) face an existential crisis when their last female fish dies, dooming their food supply. However, Ray begins experiencing unexplained physical changes-developing new reproductive capabilities, implying he is biologically evolving to ensure the survival of their micro-society. The film ends with Billy accepting this transformation, suggesting a new phase in their relationship and the possibility of continuing humanity in an altered form. The final shot lingers on the biosphere, now a fragile but hopeful microcosm of change.

Personal Opinion
Biosphere's ending is both bizarre and brilliant. The film's mix of dry humor and existential dread makes the conclusion feel earned rather than gratuitous. Ray's transformation could have been jarring, but Sterling K. Brown's nuanced performance grounds it in emotional truth. The ambiguity works in the movie's favor, leaving viewers to ponder whether this evolution is hopeful or tragic. However, the pacing drags at times, and the surreal twist might alienate some audiences. Overall, it's a bold, weird, and oddly touching take on post-apocalyptic storytelling.
Final Thoughts
Biosphere doesn't offer easy answers, and that's its strength. The ending challenges viewers to reconsider survival, identity, and human connection in a world stripped to its essentials. Whether interpreted as a sci-fi parable or a dark comedy about friendship, the film leaves a lasting impression-much like the biosphere itself, a self-contained universe of big ideas in a small space.
