-- '''WebVideo/ConfusedMatthew summarizing the film.'''

''Skyline'' is a 2010 science fiction film directed by the [[Creator/{{Hydraulx}} Brothers Strause]]. Though it made quite a bit of money at the box office, the movie has met with negative critical reception.

A young couple, Jarrod and Elaine, travel to LA for their friend Terry's birthday party at his penthouse apartment. After the wild party, everyone goes to sleep it off... only to be awoken by mysterious blue lights that fall from the sky into the city. As people are drawn to the lights in a twisted trance, they are snatched by the light, never to be seen again.

As the survivors draw the blinds to protect themselves from the light, they're faced with a dilemma: do they brave the hypnotic blue lights outside to try and escape, or do they hide in the darkness and hope that help comes for them? [[FromBadToWorse Things get worse]] when the aliens start sending out scouts to search every apartment with their blue lights, and especially when they learn what the aliens ''do'' to the people they take...

A sequel, ''Beyond Skyline'', was released in 2017.

'''Spoiler Warning''': At least one key plot element -- why the aliens are here -- could be considered a [[TheReveal Big Reveal]], but it's also intrinsic to the discussion of the work. Per Administrivia/HandlingSpoilers, blocking out 1/3rd of the examples doesn't work. So if you haven't seen the film and want to keep the alien's modus operandi a surprise, stop reading here.

!!''Skyline'' provides examples of:

* AlienAbduction: Stare into the pretty lights and a few seconds later you're being pulled into the ship.
%% * AlienInvasion
* AndThenJohnWasAZombie: [[spoiler:Jarrod]]'s brain is removed and installed into one of the war machines.
* AppendageAssimilation: The aliens can take human brains and use them as processors for their war machines. If damaged, they just grab a new brain. It looks like the rest of the body is melted down in the motherships (they throw them into a glowing pool).
* AssholeVictim: Basically the entire named cast with the exception of Jarrod and Elaine. Terry is an obnoxious womanizer, his girlfriend is a [[ItsAllAboutMe self-absorbed]] GoldDigger, the girl he cheats with is an obvious groupie, and Oliver, despite being the OnlySaneMan, remains antagonistic and condescending for most of his time in the film.
* AttackDrone: Alien "Hydra" drones that search the skyscrapers, as well as the smaller, octopus-type things, which are actually ''called'' "Drones". Also used by the military in an attack against the large ships.
* TheBadGuyWins: Sure, [[spoiler:Jarrod]] ''may'' get a somewhat happy ending if [[spoiler:Elaine]] and him can escape the ship, but these aliens have killed most of humanity already, and it's implied they aren't going to leave... at least until they run out of humans, at any rate.
* BigDamnHeroes: Jarrod gets one of these [[spoiler: at the very end when he rescues Elaine while in a superhuman alien body.]]
* BizarreAlienBiology: The aliens appear to be biomechanical, and most have an abundance of metallic tentacles and other strange appendages, and run on human brains.
* BodyHorror: Staring into the light makes your veins turn a dark, inky colour. Then you learn what the aliens want with humans -- to rip out their brains for use as biological [=CPUs=] in their war machines.
* BrainFood: Not so much eating as taking and using them for themselves. It seems to be the motivation for the invasion, since they're used to replace old ones a few times.
* BrownNote: The alien light this mixed with TheVirus.
* CliffHanger: but an interestingly inverted one. It looks like humanity, and our protagonists, are down for the count, but there is a HopeSpot in the final scene, just as we fade to black and the credits roll. Not a BolivianArmyCliffHanger, because the protagonists are left safer than they were just one minute before the ending.
* CoolShip: The alien spacecraft are huge, complicated masses of metallic spines, panels and antenna, and their blue lights do look pretty cool. [[HypnoticEyes Really... really cool....]]
* ConvenientColorChange: When [[spoiler: Jarrod]] loses their brain, it's a different color from that of everyone else thanks to having built up an immunity to their mind control. Once inserted into a giant monster, they keep control and use it to rebel.
* CurbStompBattle: It would appear humanity loses. All we see are shots of devastated cities, and even our best weapons appear to only slow them down for a bit.
* DeathByPragmatism: [[spoiler:Oliver]]. He's the most reasonable of the group, to a point, but it's his insistence on staying hunkered down in the building that ultimately spells his doom. Of course, others don't fare much better...
* DeathBySex: Played straight. [[spoiler:Terry]] is cheating on his girlfriend and gets killed. So does the girl he's cheating with.
* DevelopingDoomedCharacters: The first fifteen minutes set at Terry's birthday party, which is brimming with highly unlikeable jerks who like to spy on people having sex for their own entertainment.
* DidYouJustPunchOutCthulhu: Almost literally. Jarrod starts off with a cinderblock but then goes to fisticuffs. The alien breaks his leg during the sequence, leading to a non limb-specific BrokeYourArmPunchingOutCthulhu.
* DownerEnding:
** Humanity is done. Worse than done -- based on what the aliens did when they discovered Elaine's pregnancy and the other pregnant women nearby, humans are going to be ''farmed''.
** It's cool though. [[spoiler:Jarrod]]'s an alien war machine now and is going to kick some major alien ass in the upcoming sequel.
** For how long he's going to survive against an entire armada while trying to protect his wife is anyone's guess though.
* FacingTheBulletsOneLiner:
--> '''Oliver''': Vaya con Dios, you son of a bitch!
* FinalGirl: featuring Elaine as the very last survivor at the very end, and then quickly adverted by an inverted CliffHanger (Jarrod's resurrection as a machine).
* {{Foreshadowing}}: A possibly unintentional - and definitely musical - example here. One of the songs featured in the film is 30 Seconds to Mars's 'Kings and Queens', which is about [[spoiler:the end of the world, or at the very least, humanity]].
* GoodThingYouCanHeal: The aliens can recover from anything short of having their brains physically torn out, and even that might not stop them if they can grab a nearby human.
* HellishCopter: A Blackhawk is taken down by CombatTentacles.
* HeroicWillpower: One of the possible explanations for how [[spoiler:Jarrod]] gains control over the machine, rather than just being the CPU.
* HopeSpot:
** As it turns out, nuking the alien ship really worked! [[spoiler:Until it starts repairing itself.]]
** Played with ''and'' subverted, as whenever the main group tries to have a bit of this, they always seemed to get screwed either way. [[spoiler:Finally played straight on the ending.]]
* ImplacableMan: The Film/KingKong sized Tankers. One of them survives being hit with a rocket launcher, shot with an M-16, falling off a building, shot with several .50 BMG sniper rounds, getting caught in a gas explosion, falling off a building (again), and getting shot with an F-22's Vulcan. Having the F-22 crash into it, however, seems to kill it.
* IWillOnlySlowYouDown: [[spoiler:Jarrod]] tries this with [[spoiler:Elaine]], since he can barely move. She chooses to die with him instead by looking into the light. [[FromBadToWorse Only they don't die.]]
* LightIsNotGood:
** And blue light on top of that, to subvert GoodColorsEvilColors.
** Heck Jarrod even gives us Kind Red Eyes to counter the subverted Blue Eyes of Goodness
* LivingShip: [[http://www.wired.com/underwire/2010/11/skyline/?pid=1929&viewall=true According to]] WordOfGod, "Every single one is a different unique creature with its own DNA."
* AMillionIsAStatistic:
** The abduction of the rest of the population of Los Angeles is merely a backdrop for the drama of a very small group of people and their tragedies.
** Human military aircraft, mostly manned, getting knocked out of the skies in the background becomes almost routine by the time [[spoiler: Jarrod and Elaine]] are taken into the ship.
* MindControlEyes: Looking directly at the pretty blue lights induces this. [[spoiler:Jarrod]] also gets them when he gets pissed off later in the movie.
* MistakenForQuake: When the aliens attack, some of the characters assume it's a minor earthquake.
* NoEnding: The film fades out mid-scene.
* NoOSHACompliance: This happens so often in films that it's not funny, but rooftop doors are supposed to have a one-way lock. They lock on the inside of the building to keep people from going out on the roof (and jumping), but they ''do not lock on the outside so no one who is already out of the roof gets locked out'' in cold/rain (and aliens, by extension).
* NotUsingTheZedWord: The aliens are only referred to as "they."
* NuclearPhysicsGoof: Oliver was looking at a nuclear explosion ''through a telescope''. You're not supposed to look at the sun through a telescope, certainly not a nuclear explosion. That eye should be at the very least temporarily blinded - or more realistically - permanently.
* NukeEm: The US military attempts to nuke an alien ship. It works, but it quickly starts repairing itself, and eventually appears as good as new.
* OffWithHisHead: The aliens steal brains, taking the entire head and most of the spine with it.
* OminousFloatingSpaceship: All over the sky of every major city, apparently.
* OrganicTechnology: The aliens. WordOfGod has it that the Motherships are organic too, in spite of the fact that they ''really'' look like they're made out of gold and glass.
* ParkingGarage: When they get there, people start to die.
* PeopleFarms: It's implied that the aliens are doing this at the end of the film, since they have a contraption apparently designed to suck unborn children right out of the mother.
* PullingThemselvesTogether: The alien mothership -- even after being nuked.
* PowerAtAPrice: At the end of the film, [[spoiler:Jarrod is immune to the alien bio-tech reprogramming, and retains his personality]]. While that does grant the strength and speed of the bad guys, the downside is... you're stuck as one of them.
* RammingAlwaysWorks: The Hydras fight human aircraft by ramming into them at top speed. This leaves the Hydra unharmed...[[FridgeLogic even though getting hit with a missile will kill one.]] In an unintentional instance of this trope, the Tanker seems invulnerable to anything short of having an F-22 crash into its head.
* RealityEnsues: A really brutally honest example. So a super advanced alien race invades Earth? How will humanity fight off these powerful foes? [[spoiler: They don't. You didn't ''really'' think humanity stood a chance against alien beings advanced and powerful enough to travel across millions miles to fuel their unstoppable war machines did you?]]
%% * RedHerring: The yacht.
* RuleOfCool: Who knew such an alien invasion with no hope would somehow be exciting?
* ShootOutTheLock: Subverted. When and Jarrod are trapped on the roof by a one-way door, Terry tries to shoot out the lock twice with no success. It takes Elaine opening the door from the other side for them to escape.
* SlowNo: Jarrod, when the helicopter crashes.
* SomethingOnlyTheyWouldSay: [[spoiler:Jarrod]]'s CharacterTic of [[spoiler:stroking Elaine's face downwards from her forehead to her chin]] helps her to recognise him after [[spoiler:Jarrod's brain transplantation]].
* StarfishAliens: They sure don't look like anything on Earth.
* TaintedVeins: From looking into the blue lights.
* TakingYouWithMe: [[spoiler:Oliver]] tries this on one of the "Tanker" aliens. It doesn't work.
* TooDumbToLive: With LA full of alien monsters eating everything that moves, our heroes decide to try and escape in cars with big, growly engines and in broad daylight. Granted, their chances weren't all that good whatever they tried, but at least on foot and at night they had some small hope of evading detection. And let's not even think about the fact that their entire daylight plan was to escape by boat. From flying aliens. Yeah, that will work!
* TooSpicyForYogSothoth: [[spoiler:Jarrod]]'s glowing red brain proves to be just too much for the war-machine husk and he takes it over. Not quite the normal version of the trope, but close enough.
* TouchedByVorlons: Albeit horribly underused here.
* TrailersAlwaysLie: The trailers and commercials contained snippets of news broadcasts talking about "Every city in the world" being attacked. These never appear in the film.
* TrailersAlwaysSpoil:
** Arguably the best surprise in the film is [[spoiler: when the car is crushed by the alien's foot as it comes out of the parking garage]], so [[SarcasmMode of course]] this was displayed prominently in the trailer.
** One of the commentary tracks laments the fact that the helicopter getting grabbed while it's [[spoiler: attempting to pick up Jarrod]] would have been a nice shot if it was wasn't used in the trailers.
* TheVirus: The light seems to act like this, particularly for Jarrod.
* WilhelmScream: When a soldier gets knocked off a building. Pretty disturbing version, too.
* YourPrincessIsInAnotherCastle: Yeah, we had to nuke L.A., but the alien mothership is down... what do you mean the film is only half over?

Oooh... look at [[MindControlEyes the pretty blue text]]...
