About 10,000 years ago, peaceful aliens from the planet Antarea set up an outpost on Earth on Atlantis. When Atlantis sank, twenty aliens were left behind, kept alive in large rock-like cocoons at the bottom of the ocean. A group of Antareans have returned to collect them. Disguising themselves as humans, they rent a house with a swimming pool and charge the water with "life force" to give the cocooned Antareans energy to survive the trip home. They charter a boat from a local captain named Jack, who helps them retrieve the cocoons. Jack spies on Kitty, a beautiful woman from the team who chartered his boat, while she undresses in her cabin, and discovers that she is an alien. After the aliens reveal themselves to him and explain what is going on, he decides to help them.

Next door to the house the Antareans are renting is a retirement home. Three of its residents, Ben, Arthur, and Joe, often trespass to swim in the pool. They absorb some of the life force, making them feel younger and stronger. Eventually caught in the act, they are given permission to use the pool by the Antarean leader, Walter, on the condition that they do not touch the cocoons or tell anybody else about it. Rejuvenated with youthful energy, the three men let the advantages of the pool take hold as they are relieved of their ailments.

Kitty and Jack grow closer and decide to make love in the pool. Since she cannot do so in the human manner, she introduces him to the Antarean equivalent, in which she shares her life force energy with him.^[10]

The other retirement home residents become suspicious after witnessing Ben's wife Mary climb a tree. Their friend Bernie reveals the secret of the pool to the other residents, who rush to the pool to swim in its waters. When Walter finds them damaging one of the cocoons, he ejects them from the property. The Antereans open the damaged cocoon, and the creature inside shares his last moments with Walter. That evening, Bernie finds his wife Rose has stopped breathing and carries her body to the pool to heal her, only to be informed by Walter that the pool no longer works due to the other residents draining the life force in the rush to make themselves young.

Walter explains that the cocoons cannot survive the trip back to Antarea, but will be able to survive on Earth. With the help of Jack, Ben, Arthur and Joe, the Antareans return the cocoons to the sea. The Antareans offer to take residents of the retirement home with them to Antarea, where they will never grow older and never die. Most of them accept the offer, but Bernie chooses to remain on Earth.

Upon leaving, Ben tells his grandson David that he and Mary are leaving for good. As the residents are leaving, David's mother Susan finds out about their destination and drives to the retirement home, where they find the majority of the rooms vacant and contact local authorities.

While the police are searching for the residents, David notices Jack's boat, with the Antareans and the retirement residents aboard, starting and jumps onto the side as it pulls away. The boat is chased by the Coast Guard, so with little time left, David says goodbye to Ben and Mary before jumping into the water. The Coast Guard boats stop to pick him up, giving the others a chance to get away. A thick fog appears and strands the remaining Coast Guard boats, and they call off the chase.

As the Antarean ship appears, Walter pays Jack for his services and the boat. Jack embraces Kitty for the last time and they share a kiss. He then says farewell to everyone before jumping into an inflatable raft as the boat rises up into the Antarean vessel. Jack watches as the boat disappears inside the ship and departs.

Back on earth, a funeral is held for the missing residents. During the sermon, David looks toward the sky and smiles.

Casting for the film and its sequel was overseen by casting director Beverly McDermott.^[11]

Robert Zemeckis was originally hired as director, and spent a year working on it in development. He was at the time directing Romancing the Stone, another film for the same studio, 20th Century Fox. Fox executives previewed Romancing the Stone before its release in 1984 and hated it. That, in addition to his two previous directorial efforts, I Wanna Hold Your Hand and Used Cars, both being commercial failures (though critically acclaimed) led the studio to fire Zemeckis as director of Cocoon. He was replaced with Ron Howard.

Location filming took place in St. Petersburg, Florida, between August 20 and November 1, 1984.^[12]

Wilford Brimley was only 49 when he was cast as a senior citizen, and turned 50 during filming; he was as much as 26 years younger than the actors playing the other elderly characters. In order to look the part, Brimley bleached his hair and moustache to turn them gray, and had wrinkles and liver spots drawn on his face.^[13]

The score for Cocoon was composed and conducted by James Horner. The soundtrack was released twice, through Polydor Records in 1985 and a reprint through P.E.G. in 1997 and features eleven tracks of score and a vocal track performed by Michael Sembello. Despite the reprint, it is still considered a rarity among soundtrack collectors.^[15]

In 2013, an expanded soundtrack consisting of over 62 minutes of Horner’s score was released by the Intrada label.^[16]

The film received mostly positive critical reception. Janet Maslin of The New York Times' wrote that "Mr. Howard brings a real sweetness to his subject, as does the film's fine cast of veteran stars; he has also given Cocoon the bright, expansive look of a hot-weather hit. And even when the film begins to falter, as it does in its latter sections, Mr. Howard's touch remains reasonably steady. He does the most he can with material that, after an immensely promising opening, heads into the predictable territory of Spielberg-inspired beatific science fiction".^[17] Variety called it "a fountain of youth fable which imaginatively melds galaxy fantasy with the lives of aging mortals in a Florida retirement home [and] weaves a mesmerizing tale".^[18]

The film holds an 82% "Fresh" rating on Rotten Tomatoes from 49 critics. The critical consensus reads: "Though it may be too sentimental for some, Ron Howard's supernatural tale of eternal youth is gentle and heartwarming, touching on poignant issues of age in the process".^[19] Metacritic gave the film a score of 65 based on 18 reviews, indicating "generally favorable reviews".^[20]

The film was also a box office hit, making over $76 million in North America where it became the sixth highest-grossing film of 1985.^[21]

Accolades edit

Wilford Brimley’s age during the production and release of the film has been the subject of a popular internet meme concerning aging. Brimley, who was only 50 years old when the film was released, was relatively young to play a senior citizen. When Tom Cruise turned 50 in 2012, many juxtaposed his role in the ongoing Mission: Impossible franchise to Brimley's role in Cocoon, noting that Cruise was continuing to headline a major action franchise at the same age Brimley played an aging senior. This has resulted in the Brimley/Cocoon line meme, in which an actor who reaches 18,530 days of age (the exact age Brimley was when Cocoon premiered) has crossed it. A 2018 article in The New Yorker by Ian Crouch argued that the meme highlighted how perceptions of aging have changed since the release of Cocoon.^[31]
