TL;DR:
The ending of Cocoon (1985) sees a group of elderly residents from a retirement home, along with their loved ones, choosing to leave Earth with benevolent aliens called Antareans. The Antareans had been secretly reviving their dormant comrades from cocoons at the bottom of the ocean, using a pool infused with life-extending energy. The elderly humans, having experienced renewed youth and vitality by swimming in the pool, are offered the chance to accompany the Antareans to their home planet, where they can live forever. The film concludes with the group boarding the Antareans' spaceship, embarking on a journey to a new life, while those left behind mourn their departure but celebrate their newfound happiness.


Detailed Explanation of the Ending

The climax of Cocoon revolves around the moral and emotional dilemmas faced by the elderly protagonists - Art (Don Ameche), Ben (Wilford Brimley), and Joe (Hume Cronyn)—and their loved ones. After discovering the Antareans' secret pool, which restores their youth and vitality, they must decide whether to stay on Earth or leave with the aliens. The Antareans, who had been hiding on Earth to rescue their dormant kin, reveal that they are departing and offer the humans a place on their ship to live eternally on their utopian planet. The choice is bittersweet: eternal life means leaving behind everything they've known, including family members who either cannot or choose not to go.

The emotional weight of the ending lies in the characters' farewells. Ben, who has rekindled his marriage with his wife Mary (Maureen Stapleton), must say goodbye to his grandson David, who stays behind. Similarly, Art, who has rediscovered his zest for life, leaves behind his skeptical friend Bernie (Jack Gilford), who refuses to believe in the aliens' benevolence. Joe and his wife Alma (Jessica Tandy) also depart, embracing the chance for a new beginning. The scene where the group boards the spaceship is both joyous and melancholic, underscored by the realization that they are trading their mortal lives for an unknown but promising future.

The film's final moments shift to the perspective of those left behind. David, Bernie, and the retirement home's staff watch as the spaceship ascends into the sky, their reactions a mix of awe, sadness, and acceptance. The movie implies that while the departed have chosen immortality, those who remain must continue living with the consequences of their choices. The pool's energy is depleted, symbolizing the end of the miraculous interlude and the return to normalcy for Earth. The ending leaves viewers contemplating themes of aging, mortality, and the human desire for transcendence.

Personal Opinion on the Ending & the Film

Cocoon's ending is both uplifting and haunting, masterfully balancing hope and loss. The idea of elderly individuals being granted a second chance at life is profoundly moving, especially given the film's gentle handling of themes like aging and regret. However, the departure also feels isolating-those left behind must grapple with the absence of their loved ones, and the audience is left wondering whether eternal life is truly a blessing or just another form of escapism.

The film's strength lies in its emotional authenticity. The performances, particularly by Ameche, Brimley, and Cronyn, make the characters' decisions feel earned and deeply personal. The sci-fi elements serve as a metaphor for the universal longing for renewal, making Cocoon more than just a fantastical tale. While the ending is satisfying, it also leaves enough ambiguity to provoke thought long after the credits roll.

Ultimately, Cocoon is a poignant exploration of what it means to grow old and the sacrifices we make for a chance at something greater. Its ending is a testament to the idea that life's greatest adventures sometimes require leaving everything behind-a message that resonates across generations.
