->''It is everything you've dreamed of.''
->''It is nothing you expect.''

A 1985 sci-fi/fantasy film directed by Creator/RonHoward.

A group of trespassing senior citizens get more than they bargained for when swimming in the neighbors' pool restores their health and gives them youthful vigor. Unbeknownst to them, a group of Antareans on a search-and-recover mission to retrieve twenty cocoons containing their crew mates from the ocean floor are renting that house and using the pool to store their cocoons, and when the two groups come together, everyone involved has to make major decisions that will affect the future for all of them.

Followed by a 1988 sequel (''Cocoon: The Return''), which was not directed by Ron Howard but ''did'' reunite the entire original cast. Not to be confused with another ''[[VideoGame/FinalFantasyXIII Cocoon.]]''
!!These movies provides examples of:

* AliensInCardiff: Well, [[OnlyInFlorida Coral Gables, FL]].
* AlienLunch: Sort of. In the second movie, Jack and Kitty eat at a restaurant, with [[IntoxicationEnsues bad results]] for Kitty.
%%* AncientAstronauts: Guess!
* {{Atlantis}}: Walter thought it would be the perfect spot for their first base here on Earth.
--> '''Walter''': Everyone else said, "use the North Pole", and I said, "no, too cold". ''Sinking'' never occurred to me.
* BadassGrandpa: The old people once they swim in the pool.
** Hume Cronyn, in a meta sense. See EnforcedMethodActing.
* CassandraTruth: Art, Ben, Joe, and Bernie are told to keep breathing oxygen when they claim to have seen aliens.
* DistractedFromDeath: [[spoiler:Rosie dies in the first movie when Bernie leaves her side just long enough to get some pills and water for her.]]
* DittoAliens: The Antareans, to such an extent that [[spoiler: Kitty can easily impersonate Phil]] in the second movie.
%%* DramaticAlienVTOL
%%* FlyingSaucer: Of course!
* FountainOfYouth: By way of [[AppliedPhlebotinum the pool the Antareans set up for their cocoons]].
* FullBodyDisguise: The Antareans.
* GRatedDrug: Jack and Kitty's dinner in the second movie [[IntoxicationEnsues ends badly]].
* GRatedSex: Antareans have sex by "sharing themselves" (exchanging energy). Evidently it's "very fulfilling".
* HealingHands: Kitty fixing Jack's broken foot.
** In the second movie, [[spoiler: Joe gave up his life energy to save Alma's life]].
* HumanityIsInfectious: Walter, [[spoiler: when the newly-uncocooned Antarean dies in his arms]]. For the first time in his [[TimeAbyss very long life]], he [[spoiler: cries]].
* IChooseToStay: [[spoiler: Bernie chooses to remain on Earth]].
* InNameOnly: The first movie was based on an unpublished novel, which was eventually published as the film's {{Novelization}}. Aside from the names of the characters, it's pretty different. The second movie's novelization followed on from the plot of the first, diverging even further from the plot of the movie it was [[InNameOnly ostensibly based on]].
* InnocentAliens: When [[spoiler: one of the cocoons dies]], Walter confesses to Ben that he has never [[spoiler: lost anyone close to him before]].
* InterspeciesRomance: Jack and Kitty, again.
* IntoxicationEnsues: Some human foods don't agree with Antareans!
* {{Jerkass}}: The orderlies are real assholes.
* MayflyDecemberRomance: Have we mentioned Jack and Kitty? [[DepartmentOfRedundancyDepartment I'm pretty sure we have]].
* MohsScaleOfScienceFictionHardness: Pretty soft.
* MotherlyScientist: Sara, in the second movie, acts this way towards Phil.
* NeverTrustATrailer: The [[http://www.youtube.com/watch?v=RcNV1U8ppn4 teaser trailer for ''Cocoon II: The Return'']] is made up of recycled footage from the first film plus a scene of Jack on his boat that never appears in the actual movie. And Jack has a different boat in the movie, too.
* OlderThanTheyLook: The Antareans.
** Inverted by Creator/WilfordBrimley, who was only fifty years old when the first movie was made. He had to have his hair colored white to look old enough to be a senior citizen!
* ThePeepingTom: How Jack discovers that Kitty is an alien.
* PhosphorEssence: In their true forms (after taking off their human disguises) the Antareans glow brightly.
* PrecisionFStrike: Ben, when they discover that the neighbors are aliens: "Open the f**kin' door, Lefkowitz!"
* RagingStiffie: One of the side effects of the pool.
* ShoutOut: "[[Franchise/StarWars May the Force be with you]]!"
** In the DVDCommentary, Ron Howard mentions asking Creator/GeorgeLucas for permission to use that line. Lucas let him use it because, "you were good in ''Film/AmericanGraffiti''".
* StayWithTheAliens: Ben and Mary, Alma and Joe, Art and Bess.
* TakeMeToYourLeader: Reversed when Ben gets Pillsbury to take him to see Walter to negotiate the use of the [[FountainOfYouth swimming pool]] for himself and his friends.
* TheyWouldCutYouUp: Said almost word-for-word by Jack in the second movie when [[spoiler: a team of scientific researchers manage to get their hands on a cocoon]].
* TimeAbyss: The Antareans, again.
--> '''Walter''': Every ten or eleven thousand years or so, I make a terrible mistake.
* TrailersAlwaysSpoil: [[http://www.youtube.com/watch?v=s9BSsIX2j7M One trailer]] explicitly revealed that Walter, Kitty, et al were aliens.
* TwoPersonPoolParty: Jack and Kitty, yet again.
* UnusualEuphemism: Ben, talking about his RagingStiffie: "Blue steel. Cat couldn't scratch it!".
** Counts as a ThrowItIn. Ron Howard says in the DVDCommentary that Wilford Brimley just made that up on the spot, and they decided to keep it.
