->''"This is a Class 1 quarantined planet. The threats we will be facing are real. Everything in this planet is evolved to kill humans. Every single decision we make will be life or death."''
-->-- '''Cypher Raige'''

''After Earth'' is a science-fiction film starring Creator/WillSmith and his son Jaden Smith, the second movie to star both Smiths after ''Film/ThePursuitOfHappyness''. It was released on May 31, 2013.

Father and son, Cypher and Kitai Raige, are the sole survivors of a spaceship that crashed on a DeathWorld, Earth. Now they must survive long enough to activate the distress beacon in the wreckage of their ship.

The original story idea comes from Smith himself, though he hired a screenwriter to develop the idea more thoroughly. The film's director, Creator/MNightShyamalan, also made a few passes at it, although his involvement is so downplayed that it isn't mentioned in any of the trailers.
!!Danger is real, these Tropes are a choice:

* AFatherToHisMen: General Cypher Raige is respected and looked up to by his fellow rangers, including one who was apparently saved by him from an Ursa.
* AbusiveParents: The dinner table scene goes a bit too far with Cypher's aloofness to his son, making him seem like this instead, especially when you learn the reason for it is that [[spoiler:he resents Kitai leaving his sister to be killed by an Ursa, when he would have undoubtedly just been killed himself if he'd stayed, especially since at that point in his life Kitai was a CHILD while his sister was a trained Ranger.]]
* AfterTheEnd: The setting of the film is set a thousand years after humans almost destroyed Earth by environmental mismanagement and were forced to emigrate to another planet, where they encountered a hostile alien species with which they entered into a prolonged war. Exactly what happened is explained in supplemental material.
* AllThereInTheManual: In regards to the {{backstory}} of [[http://afterearth.wikia.com/wiki/Timeline AE's fictional universe]].
* AntiTrueSight: The alien monsters can detect humans by smelling the pheromones released by fear, Ghosting is a technique in which the subject feels no fear and becomes invisible to the monster.
* ArtisticLicenseBiology: Evolution does not work that fast. Biological changes on the scale depicted take millions, not thousands of years, and most plants and animals would have gone extinct trying to adapt to temperatures that fall far below freezing each night. In the time it would take for animals to change that much, humans would have changed significantly as well. Also, why would the animals continue evolving abilities to efficiently kill humans if humans don't even live on Earth any more?
* ArtisticLicensePhysics: A little thing called the greenhouse effect renders wild temperature swings like those seen in the movie impossible. Besides which, if such temperature swings were possible, then the trek to the tail would be impossible on account of the massive superstorms rendering the path impassable.
* AwesomeMcCoolName: Smith the Elder's character's name: ''Cypher Raige''. However, many note that it's such a ridiculous name that it loops back around to being WhoNamesTheirKidDude.
* BearsAreBadNews: "Ursa" is the Latin word for bear and the Ursa is certainly bad news.
* BigSisterInstinct: Senshi cared dearly for her little brother. She spent her last moments protecting him from an Ursa.
* BlatantLies: Kitai begins his quest with a pack of potion devices that enhance his respiratory system but two bottles get broken on the way. He lies about it to Cypher when told to report his inventory, but Cypher can tell from Kitai's heart rate that something's wrong and demands proof the next time he orders a report.
* BodyHorror: Kitai is bitten by a leech-like creature that causes a gruesome infection in his hand. Also, the way the Ursa sets up traps to frighten its human prey certainly count. [[spoiler:It impales them on tree branches.]]
* BreathWeapon: The Ursa can launch an acid-like projectile from their mouths.
* BrickJoke: Kitai asks if whales were real early in the film, because he's been reading ''Literature/MobyDick''. The final shot of the departure from Earth pans from land to the ocean, where dozens of supersized whale backs can be seen cutting through the waves.
* ChameleonCamouflage: The Ursa can go invisible, and decloak when they strike, presumably to get a better bead on their now-spooked target.
%%* ClimacticVolcanoBackdrop
* ConvectionSchmonvection: Kitai takes refuge in a cave with a ledge overlooking an active lava flow and is no worse for wear, and even ''lights a campfire'' to make it cozier. Later on, after nearly freezing to death in the wilderness, he runs and jumps up the side of an active volcano, coming within feet of large cracks that glow with the heat of the lava.
* CoolBigSis: Kitai's big sis, Ranger Senshi. She was killed by an Ursa protecting him as a child.
* DeathWorld: Earth has become one, with the planet's ecosystems being dangerous to the now offworld-living humans. (However, only one of the animals that attacked Kitai -- the leech -- did so without provocation. He threw a rock at the baboon, challenged the cat, and the eagle... had its own reasons.)
* DoNotTryThisAtHome: Do not attempt to be outside in an ash cloud, especially without a breathing apparatus. Volcanic ash particles turn to cement when they are inhaled, causing rapid suffocation.
* DoubleMeaning: "Where is my son?" from a father who is disappointed his son failed to become a ranger. "I've lost contact with our son." Cypher brought Kitai on the mission to establish contact with his son.
* DreamSequence: Kitai goes to sleep on a raft floating down a river. It is immediately clear that he is dreaming, as his sister is there.
* DullSurprise: All throughout the film, mostly from Will Smith of all people.
* EarthThatWas: Earth as a planet is fine, it's just that it isn't inhabited by humans anymore.
* EverythingTryingToKillYou: The wildlife of Earth for reasons explained in the backstory and reasons gradually revealed in the movie. This was played up in the trailer, but [[TrailersAlwaysLie in the actual film the animals didn't behave this way at all.]]
* EyelessFace: The Ursa, completely blind monsters that have been genetically engineered to hunt humans by the smell of the pheromones released when a human becomes frightened.
* FinaglesLaw: Cypher estimates that the chances of the Ursa surviving is the least likely. Guess what actually happens.
* {{Foreshadowing}}: Kitai tells his father he is reading Moby Dick, a novel about a physically disabled captain pursuing a monster. [[spoiler:Guess what happens to the commander of the ship?]]
* GeneralBadass: General Cypher. In the beginning of the film, he becomes the first Ranger capable of ''ghosting'', showing no fear whatsoever, and thus rendering himself invisible to the Ursa.
* GenerationXerox: After [[spoiler:the death of his Ranger sister]], Kitai wants to become a Ranger (and possibly a Ghost too) so that his father has someone to be proud of.
* GreenAesop: Apparently humans screwed Earth up so badly that it was uninhabitable. However, when Kitai sees Earth, it's a world of stunning vistas and incredible wildlife--within just a thousand years, nature has reclaimed the world and cleaned it up rather nicely. So along with an environmental message, the film also lets us know that nature's tougher than we suspect. That said, the wildlife is much bolder than while humans lived there. They're not actually "evolved to kill humans", but they're perfectly capable of killing them anyway.
* HappyFlashback: Both Cypher and Kitai have a couple of flashbacks to happier times with their family.
* HeroicSacrifice: [[spoiler:The giant bird that took Kitai to its nest earlier in the film saves him after he fails to reach a hot spot. Most likely because of his attempts to save its chicks from the cats earlier. It dies in the process of keeping him warm.]]
* HollywoodTactics: The strange tactics implied to be in use (such as favouring mêlée weapons over ranged ones) are {{justified}} since the film is set in a human culture that's trying to avoid ultra-high-tech dominance, preferring organically-dominant technology with as little high-tech as they want to risk. This allows for stylized action sequences involving the use of swords/spears, martial arts, and agile chase scenes.
* HowWeGotHere: The opening shot shows Kitai awakening after the ship's crash. Then the movie cuts back to three days earlier, explaining how he ended up there.
* ImNotAfraidOfYou: Because they track down prey using fear pheromones, if the target is unafraid, the Ursa is blind to them. Suppressing all fear for this purpose is known as "ghosting".
* ImpaledWithExtremePrejudice:
** The Ursa takes bodies of people it has killed and impales them on tree branches, letting survivors know it's around to get them good and scared.
** At the climax of the movie, [[spoiler:after Kitai learns how to "ghost" like his father, he stabs the Ursa multiple times.]]
* InformedAbility: For a world where "everything has evolved to kill humans", there is remarkably little that's actually hostile. Apart from the Ursa, and the wildlife doesn't seem any more dangerous than what we have today.
* KidnappingBirdOfPrey: It's never quite clear whether the eagle wanted to feed Kitai to her chicks or [[spoiler:adopt him.]]
* LivingWeapon: The Ursa, a species genetically engineered by the unnamed aliens antagonizing humanity to hunt humans by smell. They look like six-legged ''things'' as large as elephants with smooth skin where their eyes should be.
* MamaBear: Do ''not'' come between the giant eagle and her offspring. [[spoiler:She also becomes protective of Kitai after she loses all her chicks, watching over him from above and saving him from freezing to death.]]
* MissionControl: Cypher spends most of the film confined to the wreckage of the fore of the crashed spaceship, where he takes pains to always maintain the cool, detached façade of a military commander.
* MookHorrorShow: The Ursa kills about twenty baboons for no apparent reason, leaving their carcasses in a heap.
* MorphWeapon: The Cutlass; its unique design extends its sharp bladed ends in a variety of shapes which can be chosen by the holder, each blade shape seemingly fitting a different style of attack.
%%* MrExposition: The main reason for Cypher to be in the movie.
* NobleBirdOfPrey: A giant eagle is one of the inhabitants of the new Earth. It fights off an ''entire pack'' of predatory cats!
* NoEscapeButDown: Kitai has to jump off a cliff in order to safe himself from a tiger-like beast.
* PantheraAwesome: Some sort of big cats attack the eagle nest. They don't go after Kitai, though; they're more interested in the helpless baby birds. They only attack Kitai when he decides to defend the eaglets.
* RedshirtArmy: Most of the crew of the transport ship is just there to be killed by either the crash or the Ursa.
* {{Retirony}}: The mission that led to Cypher and his son crash-landing on Earth was supposed to be Cypher's last voyage before retirement. [[spoiler: Subverted, as he is severely wounded but survives]].
* RuleOfDrama: The only reason there is so much soul-searching and bickering about the past when the main characters should instead be focused on survival is because it's dramatic.
* SceneryPorn:
** When not being attacked by the extremely dangerous fauna, the landscapes of Earth are absolutely breathtaking.
** Nova Prime is richly designed, particularly after building the human settlements.
* SpaceAmish: [[AllThereInTheManual The background material]] states that a new religion was founded which opposes industrialization. The Rangers seem to have a particular aversion to projectile weapons -- the only weapon they are shown using are their shape-shifting "Cutlass" melee weapons.
* SpiritualSuccessor: To ''Film/BattlefieldEarth'' - the slightly surreal sci-fi Happyology-themed vanity project of a big Hollywood star in which he plays a supporting major character, which was made with the intent of making a sequel which will never come.
* TheStoic: Cypher Raige has gotten so used to suppressing his emotions that he turns into this. He still has emotional outbursts from time to time, but he keeps emotions to a minimum for the most of the movie.
* SuperPersistentPredator:
** Subverted with regards to the giant bird. [[spoiler:After Kitai attempts to protect the bird's chicks, it follows him, and ultimately sacrifices itself to keep him warm after he passes out from the freezing temperatures.]]
** The Ursa impales some of the crew on the ship to cause fear in Kitai so it can sense where he is and chase after him during the lengthy climax.
** Completely [[JustifiedTrope justified]] with regards to the Ursa in general, because the Ursas were created ''specifically'' to hunt and kill humans.
* TranquilFury: What General Cypher and later Kitai display when taking on the Ursa. They are both eerily calm while there are giant monsters thrashing around them, and in the former's case, people being killed.
* VeryLooselyBasedOnATrueStory: Smith was reportedly inspired by an episode of the RealityTelevision/documentary show ''I Shouldn't Be Alive''. The episode in question featured a father-and-son duo who crashed their car in a remote area, with the son having to go for help alone.
* TroubledBackstoryFlashback: The film often cuts to scenes taking place in the past, all involving [[spoiler:Ranger Senshi, Kitai's deceased elder sister]].
* VoiceWithAnInternetConnection: Cypher is injured in the crash, requiring Kitai to venture out alone with a two-way communicator that lets his father see everything that's going on and remain in constant contact with Kitai.
* WhatTheHellIsThatAccent: All the humans speak in a strange quasi-Boston affected accent that's supposed to be some sort of "future English." Depending on the actor, the accent sounds like a weird mix between General American, British RP, a hint of India, some influences from Ebonics, and a little kid's slurred speech. Of course, this might just make sense, since humans left Earth together.
