->'''Ironhide:''' ''Why are we fighting to save the humans? They're a primitive and violent race.''
->'''Optimus Prime:''' ''Were we so different? They are a young species. They have much to learn... but I've seen goodness in them. Freedom is the right of all sentient beings...''

''Note: This is about the live-action'' '''Franchise/{{Transformers}}''' ''films. For the 1986 animated [[TransformersGeneration1 Generation One]] movie, see'' '''WesternAnimation/TransformersTheMovie'''''.''

The first in the Franchise/TransformersFilmSeries, [[LiveActionAdaptation live-action films]] based on the [[LongRunners long-running]] ''Franchise/{{Transformers}}'' toyline and television series. Produced by Creator/StevenSpielberg and directed by Creator/MichaelBay.

Our protagonist is [[OrdinaryHighSchoolStudent teenager]] Sam Witwicky (ShiaLaBeouf). He wants his first car to impress "evil jock concubine" Mikaela (Creator/MeganFox), who turns out to be [[WrenchWench rather talented with cars]]. He ends up getting a beat-up yellow Camaro. But it turns out the car chose ''him''; it's one of many [[RidiculouslyHumanRobots sentient alien robots]] who can "[[TransformingMecha transform]]" and disguise themselves as human vehicles. His name's [[KidAppealCharacter Bumblebee]], an advance scout for the Autobots, a noble faction from the planet Cybertron and whose mission is to protect Sam from another faction, the evil Decepticons.

On another front, a US military base is attacked by agents of the Decepticons, with the sole survivors handling valuable information on who they are fighting and how they can stand a chance at fighting back. At the same time, a Pentagon analyst find evidence that there is a GovernmentConspiracy that knows more of what is going on than anyone else. These plotlines converge as Autobot reinforcements lead by [[TheAragorn Optimus Prime]] arrives on Earth and tells Sam's his [[MacGuffin family heirloom]] holds answers to the location of [[MacGuffin the AllSpark]], a powerful artifact responsible for the Transformers' existence and lost for thousands of years. The two factions battle over it: the Autobots want to return life to their dying world, while the Decepticons seek to exterminate their enemies.


Here is [[Characters/TransformersFilmSeries the character sheet.]]

----
!!This film provides examples of:

* AMFMCharacterization: Bumblebee, the first Transformer our protagonist meets, actually has no real voice capabilities, and instead does all of his vocalizations through playing songs on his stereo. This is the trope cranked UpToEleven.
* BrosBeforeHoes: Inverted; Sam's friend reminds him of the trope, but he's kicked to the curb so Sam can go after Mikaela.
* CarFu:
** A rather different case than usual -- most of the Autobots turn into cars, who apparently know Kung Fu. For the first movie, in fact, Creator/MichaelBay instructed the animators to watch Kung Fu movies to get a feel for how they should move. According to the DVD extras, he even had [[WireFu martial artists on wire rigs]] filmed to visualize the combat movements of the Transformers in hand-to-hand combat.
** A more traditional case was Bumblebee's slide/drift in vehicle mode to knock down Barricade while rescuing Sam and Mikaela.
* CarSkiing: Bumblebee does this to scan and transform into the 2009 version of the Camaro.
* ChekhovsGun: Optimus outlines a plan that the only way to destroy the [=AllSpark=] is by merging it with his own spark in his chest. The idea was that eliminating the [=AllSpark=] and Optimus along with it is preferable over Megatron getting it. Sam managing to execute that plan on Megatron was definitely seen as a MillionToOneChance.
* ChestBlaster: Blackout's chest cannon, Frenzy's CD blade launcher.
* CompositeCharacter: Bumblebee has the friendliness of the classic G1 Bumblebee but combines the visual "door wings" of Prowl and the frontline soldier role of Sideswipe.
* DeadlyFireworksDisplay: [[spoiler:Blackout]]; [[spoiler:Megatron]], although to a much lesser extent.
* DecompositeCharacter: The role of Soundwave as the HypercompetentSidekick to Megatron was split between Barricade (the cop car) and especially Blackout (the helicopter), including their use of deployable minions of Scorponok and Frenzy. He was in earlier scripts, but the demands against [[ShapeshifterBaggage Mass Shifting]] lead to the role being split up and, eventually, leaving him out altogether because it wouldn't have done the character justice.
* DepletedPhlebotinumShells: The entire role of Lennox and Epps in the story was figuring out the most effective way of fighting against the Decepticons. They come to the conclusion that high heat sabot grenades do the most damage (besides [[GunshipRescue heavy artillery from a gunship]]), although it's still DeathOfAThousandCuts from regular infantry.
* DestroyTheProductPlacement:
** [[ZigzaggedTrope Zigzagged]] with the licensed vehicle modes never getting destroyed (with the exception of Sideways in the [[Film/TransformersRevengeOfTheFallen second movie]]), with the destruction/killing ocurring only when they're in robot mode;
** Inverted with the Allspark animating a Mountain Dew vending machine and an Xbox, both of which start attacking passersby.
* EBay - Sam selling his [[MacGuffin Grandfather's glasses]] there kicked the whole thing off.
* ETGaveUsWiFi: The Decepticons' ability to infiltrate Earth technology is {{Hand Wave}}d by stating that [[spoiler:all modern tech was reverse-engineered from the captured Megatron]], which would also explain why the [=AllSpark=] could be used to transform Earth's tech.
* EverythingsSparklyWithJewelry: Mojo's collar.
--> '''Mrs. Witwicky''': That's his bling!
* ExplosionPropulsion: Ironhide uses his cannons to blast himself into a vault to dodge Brawl's missiles.
* FamilyUnfriendlyDeath:
** The film had its fair share of gruesome deaths. Bonecrusher and Frenzy both getting beheaded (in Frenzy's case, [[HoistByHisOwnPetard by his own weapon]]), and just look at the mess of what was formerly Megatron's chest after the Allspark is rammed directly into his spark.
** How bout that soldier in Lennox's squad in the who got impaled in his chest by Scorponok?
** And Jazz's death.
--->'''Jazz:''' "You want a piece of me? ''You want a piece?!''"
--->'''Megatron:''' "No! I want-" *tears Jazz in half* "TWO!"
* FiveBadBand: The Decepticons.
** BigBad: Megatron, though Starscream fills in until his revival.
** TheDragon: Starscream.
** TheBigGuy: Blackout, Bonecrusher and Brawl.
** TheEvilGenius: Frenzy.
** TheDarkChick: Barricade.
* FiveManBand: The Autobots form one.
** TheLeader: Optimus Prime.
** TheLancer: Jazz.
** TheBigGuy: Ironhide.
** TheSmartGuy: Ratchet.
** TheFace: Bumblebee.
** SixthRanger: Sam, Mikaela, Epps and Lennox.
** BigGood: John Keller, just about the only high-ranking government official on the protagonist's side.
* FreezeFrameBonus: When he tries to attack Sam, Barricade disguises itself as a police car, with "To Punish And Enslave" written at the side (instead of "To Protect And Serve").
* GiantRobotHandsSaveLives: When Optimus catches Sam as he's falling from the skyscraper.
* GodzillaThreshold: The military plan to hide the [=AllSpark=] in Mission City.
* HiddenInPlainSight: Parodied when Sam asked the Autobots to back off from the house while he searched for the glasses. The Autobots transform into their vehicle modes... and sit right there in the back yard. Sam screams at them that it's not a truck-stop, and they have to hide in robot-mode. Optimus later invokes the trope in his message before the credits.
* HollywoodHacking: The entirety of the slightly-less-than-awesome "signal processing" subplot.
* HumansAreBastards: The capture of Bumblebee by Sector 7, which, coupled with them repeatedly blasting him with freezing chemical during and after the capture, has a definite feeling of torture. When Bumblebee almost shoots the engineers after they release him, it's hard to blame him.
** Some of this is even intercut with the rest of the Autobots questioning Optimus over why they should save us from the Decepticons, given how primitive and violent we are as a race. Optimus Prime reminds them that at one time, Cybertronians were NotSoDifferent from us.
* IllKillYou:
-->'''Megatron:''' I'll kill you! Mine! Allspark!
* KillItWithFire: [[LargeHam Agent Simmons]] tries to kill Frenzy this way. It doesn't work.
-->'''Simmons''': BURN SUCKER! BUURRRRRRNN!!
* TheLoad: Attempted aversion with Sam Witwicky, with the location of the Allspark is imprinted his glasses.
* MagicalNegro: Used car salesman Bobby Bolivia [[InvokedTrope attempts to act like this as a sales pitch.]]
* TheMatchmaker: Bumblebee.
* MeaningfulEcho: "No sacrifice, no victory."
* MenCantKeepHouse: Sam's room, with his suggested PornStash.
* MetaOrigin: The [=AllSpark=] is written to be described enough to explain their origins but vague enough to not answer everything.
* MightyGlacier:
** Ratchet is one of the physically strongest Autobots. He's also one of the slowest.
** Ironhide even more so.
* MistakenForMasturbating: Sam Witwicky's parents notice that he's hiding something from them. Sam's mother outright asks if he's masturbating, and his parents proceed to try to give him space.
* MomentKiller: [[InvokedTrope Invoked]] by Mikaela. Sam's parents were questioning Sam's nervous and twitchy behavior (due to the Autobots hanging out in the backyard) after coming into his room, with her trying to hide. To end the conversation Mikaela presents herself, making it seem that Sam was acting that way because they interrupted an intimate moment. Rather than being upset, [[CrowningMomentOfFunny Mom and Dad Witwicky are thrilled for Sam.]]
--> '''Judy Witwicky:''' Oh my gosh you're gorgeous! I'm sorry you had to hear our little "family discussion."
* MySensorsIndicateYouWantToTapThat:
** Ratchet's introductory comment: "The boy's pheromone levels suggest that he wants to mate with the female."
** Earlier, when Bumblebee pretends to cut out at a local make-out point, his radio starts playing Marvin Gaye's "Sexual Healing".
* NoConservationOfMass: Mostly averted, since care was taken so that the Transformers had the same amount of mass in vehicle and robot form. However, the Cube can apparently go from house-sized to basketball-sized with no release of energy. That said, the Cube is a magical MacGuffin responsible for the creation of a not just a race of transforming giant sentient machines but their entire world as well so it gets a little leeway.
* NotMakingThisUpDisclaimer: Michael Bay mentioned in the DVDCommentary that the sequence where Lennox had to deal with an obnoxious telephone operator to get a call transferred to the Pentagon while under fire was taken from a RealLife incident he heard about while talking with some military personnel.
* NotThisOneThatOne: Invoked by Sam's dad. When taking him to get his new car, he drives Sam through the parking lot of a Porsche dealer, waiting until Sam says in disbelief and excitement, "You are not getting me a Porsche!" to which Dad replies, "You're right. You're not getting a Porsche," and drives into a used car lot.
** GeniusBonus: The Porsche family has told Hasbro and Takara, makers of the Transformers toys, that their vehicles are off limits.
* OnlineAlias: "Are you ladiesman217?"
* OrdinaryHighSchoolStudent: Sam.
* PreAssKickingOneLiner: "'''Join''' them in '''EXTINCTION!'''" [[BlownAcrossTheRoom * blam* ]]
* ReasonYouSuckSpeech: Megatron to Optimus:
--> '''Megatron''': You still fight for the weak! That is why you lose!
* RuleOfCool: Giant robots... '''[[HumongousMecha Giant robots]]'''. The advertising campaign amounted to, "Look at all the cool shit they can do!"
* SealedEvilInACan: [[spoiler:Megatron is kept on ice inside the Hoover Dam, and is pretty angry upon thawing out.]]
* SelfDeprecation: On the part of director Creator/MichaelBay:
--> "This is easily, a hundred times cooler than ''Film/{{Armageddon}}'', I swear to God!!"
** [[http://www.youtube.com/watch?v=lXRCf9LbLM0 And the very famous commercial where he goes around blowing stuff up demanding that everything be awesome, including a to-scale Bumblebee statue behind him.]]
** The human that Megatron flicked was... Michael Bay himself.
-->'''Megatron:''' "Disgusting."
* ShoutOut:
** At the site where one of the Autobots crashed, we see a nerdy guy screaming "This is a hundred times cooler than ''Film/{{Armageddon}}''!"
** The scene where Captain Lennox and his team are pinned down, need to call the Pentagon over a phone and need a credit card to pay for the call is almost identical to a scene in the film ''Film/HeartbreakRidge''.
* StandardHollywoodStrafingProcedure: The A-10's that attack Scorponok are shown shredding the ground in plenty of space before and after his spot.
* StandardPoliceMotto: Parodied. Barricade's alt-mode is a police car mode with the phrase "To punish and enslave."
* StaringKid: Several, one notable one is the girl who has a transformer land in her pool.
* UnderTheTruck: Captain Lennox grabs an abandoned motorcycle in the first film, drives it straight at the Decepticon walking away, and puts it in a slide right through his legs, while firing his assault rifle and GrenadeLauncher straight into said Decepticon, killing it.
* VengefulVendingMachine: The power of the Cube animates a soda machine, which sprouts limbs and goes berserk.
* YouAllShareMyStory: The three separate subplots involving Lennox's team, the NSA hackers, and Sam and Mikaela converge when all three are assembled at the Hoover Dam for the final battle.
