* ActorAllusion:
** At one point in the game, Joel mentions that he wanted to become a singer. His actor, Troy Baker, was once the lead singer for an indie-rock band called Tripp Fontaine and has released a solo album recently.
** Nolan North also has a moment where his character (David) alludes to a line that he said in a previous work released a year before ''The Last Of Us''. During [[spoiler:his confrontation with Ellie (if you let him talk for long enough after stabbing him for the first time)]], he says "[[VideoGame/SpecOpsTheLine you brought this on yourself]]."
** Troy Baker as a badass "shoot everything on sight" kinda guy with a shady and blood drenched past, is charged to pick up and deliver a young girl who he is forced to protect from hordes of enemies while she provides backup and occasionally pipes up with helpful advice or snarky comments. Said girl also runs away from him at one point. Hmm, now [[VideoGame/BioshockInfinite where have we heard that before?]]
* ApprovalOfGod: [[https://www.youtube.com/watch?v=N6Vx6aML-cE This]] reimagining of the opening to ''True Detective'' by way of ''The Last Of Us'' got [[https://twitter.com/Neil_Druckmann/status/454276575010095104 an approving tweet from the game's creative director]].
* AscendedFanon:
** An inversion of sorts, while the original concepts for Joel and Ellie had their last names as "Miller" and "Williams", respectively (see WhatCouldHaveBeen below), Naughty Dog eventually decided to scrap all last names from the game. This hasn't stopped [[http://www.youtube.com/channel/UCcWwh4iPAOjWhBV8TD8FX7g some]] [[http://www.youtube.com/channel/UCWdAsGtHpPYdHelo42zOjLA fans]] from running with the scrapped names, however.
** Coupled with ThrowItIn: The decision to make Riley Ellie's love interest came when talking to the writer of the ''American Dreams'' prequel comics, they said that "Ellie was attracted to Riley." The writer stopped them and asked if they meant attracted as in a "digging her personality"-way, or in a "sexually attracted"-way. They then spent a couple of weeks looking back at Ellie from the game, realized that there were nothing about her that leaned one way or the other and, after a go-ahead from Ellie's actress, decided to go with it.
* {{Blooper}}: A sound-based one. When Joel interrupts Ellie from [[spoiler:hacking David to pieces, the machete can be heard hitting the ground, yet a few seconds later it's shown to be stuck in David's head.]]
* DawsonCasting: 14-year old Ellie is voiced by 30-year old Ashley Johnson. Subverted with circa 50-year old Joel who is voiced by 37-year old Troy Baker. Additionally, 16-year old Riley is voiced by 32-year old Yaani King, and Joel's little brother Tommy is voiced by Jeffrey Pierce, who is five years older than Troy.
* DeletedScene: A 2014 'Live Performance' of ''The Last Of Us'' revealed a scene that was meant to have been TheStinger, but got cut out. The scene (acted by Troy and Ashley, not animated) [[spoiler:features Joel and Ellie some few months after settling at Tommy's, where Joel visits Ellie in her room and talks a bit about a woman Tommy has been setting him up with. Ellie still acts a little down after the outcome of their journey and Joel's lie. Joel then presents a guitar and plays a song for her, with Ellie thanking him when he's done. He gives her the guitar as a present, and she playes a few notes on it after he walks out.]]
* DoingItForTheArt: Naughty Dog had to stand its ground to have Ellie feature on the game's cover, since the popular idea among publishers is that games with a female on the cover might alienate wider audiences. More about it can be read [[http://www.escapistmagazine.com/news/view/121064-Naughty-Dog-Flat-Out-Refused-to-Change-Last-of-Us-Cover here]].
* DuelingGames: Has parallels to a number of games, including:
** ''VideoGame/IAmAlive'': WeaponForIntimidation, DisasterScavengers, platforming-climbing around the RuinsOfTheModernAge, influences from TheRoad, CombatPragmatism, an older guy escorting a young girl, and so on.
** ''VideoGame/BioShockInfinite'': Both are AAA games with a heavy focus on narrative featuring guitar playing, UnscrupulousHero protagonists voiced by Creator/TroyBaker, [[spoiler:who both lost their daughter 20 years ago]] and are now charged with escorting a girl named Elizabeth or a derivative of such, teaching her the ways of the world, [[spoiler:and eventually turning against a black woman leading a revolutionary force]].
** ''VideoGame/TheWalkingDead'': Man takes care of a young girl in the midst of a zombie apocalypse.
** ''{{VideoGame/Metro2033}}''/''[[VideoGame/MetroLastLight Last Light]]'': Post-apocalyptic SurvivalHorror story set in the ruins of a former superpower nation in [[AfterTheEnd 2033]], heavy use of {{Improvised Weapon}}s, hostile environs that require a gas mask and a rechargeable flashlight, ability to choose between stealthy or loud approaches to combat, even more guitar playing, and were both games on the [=PS3=] that got remastered for the [=PS4=] in 2014.
* DyeingForYourArt: During the scenes in Winter where Ellie is roughly handled by David and James, Ashley did her own stunts and would be covered in bruises after takes.
* EnforcedMethodActing: For one take of the final cinematic (which was turned into an interactive scene in the final game), Merle Dandridge was told to deliver her lines in a certain way and Troy Baker was independently told to keep going no matter what (he had been fumbling the prop gun during most takes). You can see the result in [[http://www.youtube.com/watch?v=z8XN7eoZr0Y this]] behind-the-scenes video.
** When acting out the cutscene during Fall where Ellie confronts Joel about leaving her, Ashley pushed Troy while saying "...everyone - fucking except for you [have left her]." The push was unscripted, but Druckmann thought it fit well and let it stay.
*** It wasn't the first time Ashley had pushed someone during that line. She previously did so with another man trying out for Joel's part, with the latter being so caught in the moment he pushed her back.
* FanNickname: The infected are often jokingly referred to as "the mushroom people".
** Some people have taken to calling the time before the infection outbreak as...well, [[ExactlyWhatItSaysOnTheTin Before.]] With a capital B.
** In [[http://lparchive.org/The-Last-of-Us/ this]] LetsPlay, Geop and Skippy Granola take to calling Joel "Solomon Grumpy."
* IKnewIt: There was a RunningGag on [[Website/FourChan /v/]] that Ellie was [[StraightGay gay]] after the opening scene of the ''Left Behind'' DLC was shown in a preview, where we see Riley biting her neck to wake her up. This ended up being completely true.
* LyingCreator: [[EnforcedTrope Enforced.]] Naughty Dog felt the need to insist that [[spoiler: you only play as Joel and never as Ellie]] in interviews because they felt the twist was so crucial to the story.
* PlayingAgainstType: Creator/NolanNorth as David.
* ProductionPosse: Seeing as Creator/NolanNorth is to Creator/NaughtyDog what John Ratzenberger is to Creator/{{Pixar}}, it's inevitable that he'd show up.
* RevivalByCommercialization: The ''Left Behind'' DLC introduced many people to Etta James' 'I Got You, Babe'.
* ScienceMarchesOn: Downplayed example, but the species of ''Cordyceps'' that the infection in the game is based on is now considered to be part of a different genus, ''Ophiocordyceps''.
* ThrowItIn: Creative director Neil Druckmann revealed in [[http://www.youtube.com/watch?v=deuVinwv1os an interview]] that Creator/AshleyJohnson improvised some of Ellie's quirky humor.
* TruthInTelevision: The ''Cordyceps'' here are a mutated form of the actual fungal infection. Real ''Cordyceps'' are either endoparasites of arthropods or other fungi.
** In fact, this is even referenced in a document in-game, saying that the ''Cordyceps'' fungus originally only infected insects and some arthropods.
* WhatCouldHaveBeen:
** Tess was originally conceived as a major antagonist, harboring a grudge against Joel for betraying her in the past. More about it can be read [[http://www.escapistmagazine.com/news/view/126687-The-Last-of-Us-Originally-Cast-Tess-as-a-Villain here]].
** An [[http://www.reddit.com/r/IAmA/comments/1jg952/hi_were_neil_druckmann_creative_director_and/ AMA on reddit.com]] with game director Bruce Straley and creative director Neil Druckman revealed some interesting things:
*** Early in development, Joel's last name was given as "Miller" and Ellie's as "Williams," but [[WordofGod Neil Druckmann]] [[http://www.reddit.com/r/IAmA/comments/1jg952/hi_were_neil_druckmann_creative_director_and/cbecr5b revealed]] that the decision was made to cut all last names from the final product. These names are still listed in the Japanese [[AllThereInTheManual manual]], however.
*** Joel was originally going to be named "Ethan". [[DevelopmentGag There is a mook that Joel will kill in a cut-scene, who a pair of other mooks who come to investigate refer to as "Ethan."]]
** Joel [[spoiler:rescuing Ellie from the operating room]] was originally going to be a cutscene, which can be seen parodied [[http://www.youtube.com/watch?v=z8XN7eoZr0Y here]] (spoilers, obviously) with Troy Baker and Merle Dandridge singing the dialogue in the ending.
*** A fan actually made [[http://www.youtube.com/watch?v=6Z8P_RoKDho&desktop_uri=%2Fwatch%3Fv%3D6Z8P_RoKDho&app=desktop an orchestral accompaniment]] to it, which [[ApprovalOfGod got tweeted by Troy Baker]].
** Instead of [[spoiler:giraffes, Joel and Ellie were going to encounter a herd of deer, but the developers figured giraffes would make it more special.]]
** The game was originally going to be a ''VideoGame/JakAndDaxter'' game, but because the developers felt that they were only making it because it was an existing IP they could easily make money off of, they went to their higher ups and explained that they didn't feel like they were making the game for the right reasons and they didn't really feel passionate about it. They were then told to do what they wanted, and thus ''The Last of Us'' was born. Naughty Dog later released some of the concept art for the game in an artbook, revealing a [[http://jakanddaxter.wikia.com/wiki/Jak_4?file=Jak_4_concept_art_2.png photorealistic Jak]] and a [[http://jakanddaxter.wikia.com/wiki/Jak_4?file=Jak_4_concept_art_1.png steampunk setting.]]
** Checking out the concept art for the game will reveal many things that were considered during production. Perhaps most notably is how early designs of infected showed some of them ''carrying tools as weapons'' while others were ''merged together''. Apparently, the creators also played around with the idea of Ellie having a dog.
** "Left Behind" has its share of ideas which either didn't make it or were heavily reworked. Some of which were revealed in [[http://www.ign.com/articles/2014/02/14/the-last-of-us-left-behind-spoilercast-podcast-beyond-episode-329 this interview with Druckmann and Straley on IGN]]:
*** They toyed with the idea of including a note written by [[EnsembleDarkhorse Ish]]; but eventually decided not to, as it would've been little more than PanderingToTheBase.
*** Originally, the DLC wasn't even going to show the moment where [[spoiler: Riley and Ellie get bitten.]]
* WordOfGay: Neil Druckmann [[http://gaygamer.net/2014/02/is-ellie-gay-naughty-dogs-neil-druckmann-weighs-in-on-the-last-of-us-left-behind/ on Ellie and Riley's relationship]]:
-->''“Now when I was writing it I was writing it with the idea that Ellie is gay, and when the actresses were working they were definitely working with the idea that they’re both attracted to each other. That was the subtext and intention that they were playing with from the opening cinematic when they’re holding each other’s hands for too long, or when Riley bites her on the neck; there’s that chemistry there from the get go that was important for us so that we earned that moment when they kissed each other. So that it wasn’t just out of the blue but also wasn’t so overt that you’re like “Oh of course. Just get on with it.”''
** The creators are pretty adament that she was conceived as a lesbian during their initial pitch, but they couldn't figure out how to have her say that to Joel, and thus the player, during the main game; or have her mention that to herself during the Winter-chapter. And so they put it on the "maybe"-pile. And then came the DLC...

!! Misc. Trivia
* Both Neil Druckmann and Troy Baker have shown interest in Creator/JoshBrolin to play Joel in the movie adaptation, while Ashley Johnson's own personal choice for Ellie is ''Series/GameOfThrones'' actress Creator/MaisieWilliams, to which said actress has stated that she'd be very happy to play her. Whether these are the actors that will actually end up in the roles however remains to be seen.
** Creator/HughJackman is rumored to be considered for the role of Joel as well.
* Ellie and Joel's conversation while in the car headed for Pittsburgh, while happening towards the middle of the game, was the first scene Ashley and Troy tried out for together.
