* Phoenix gets very emotional while watching final scenes of ''[[Film/ReturnoftheJedi Return of the Jedi]]''.
* Presenting a wrong piece of evidence during cross-examination in most cases will result in the following gem:

-->'''Wright:''' I object to this testimony!
-->'''Judge:''' You do? Why?
-->'''Wright:''' [[Film/LiarLiar Because it's detrimental to my case!]]
-->'''Judge:''' Overruled!
-->'''Wright:''' Good call!
* Sir Gallante appears to share some traits with known superheroes like for example ComicBook/{{Batman}} (he performs [[BuildingSwing buliding swings]] and is a ''dark knight'' after all) and ComicBook/ThePunisher (he actually kills the criminals that he fights and his iconic symbol is a skull.)
** Don't forget the defendant is named [[ComicBook/{{Batman}} Wayne]] [[ComicBook/SpiderMan Parker]], and a side character is named [[ComicBook/IronMan Tony]] [[ComicBook/{{Superman}} Kent]].
* Morton Dreisan, the police coroner makes a cheesy joke about the deceased in the Series/CSIMiami style:

-->'''Morton:''' It was a single bullet, straight to the cerebral cortex!
-->...I suppose you might say... that he "lost his mind"...!
* The sender of the email on the woman's computer is [[VideoGame/ProfessorLaytonandtheDiabolicalBox krantz@folsensehostel.net]]
* Conversations with Gladys Porter are usually full of various references:

-->'''Gladys:''' Well, OBVIOUSLY it's because I'm the very best reporter ever.
-->'''Phoenix:''' The very best...
-->'''Gladys:''' Yeah! ... [[Anime/PokemonTheSeries Like no reporter ever was!]]

-->'''Phoenix:''' My quest... my goal is to find the truth, no matter what it may be.
-->'''Phoenix:''' No snarky comebacks?
-->'''Gladys:''' [[Series/TheXFiles The truth IS out there]]. You're not the only one who wants to find it.
-->'''Phoenix:''' Yeah, well my truth doesn't involve whatever they're holding at Area 51.
* In Turnabout Consequences, when Phoenix asks about Bikini's relationship with the Fey Family:

-->'''Phoenix:''' So, how exactly is Bikini related to you?
-->'''Phoenix:''' She's part of the Fey clan, so there must be some relation, right?
-->'''[[spoiler: Pearl]]:''' Oh...? I don't know.
-->'''Phoenix''' (thinking): [[Film/{{Spaceballs}} Father's brother's nephew's cousin's former roommate]], perhaps? Would somebody else know the answer to this?

* One dialogue with Raphael Donatello has him state that he was "[[Franchise/TeenageMutantNinjaTurtles raised in the sewers and taught the art of ninjitsu]]."
* In Finnegan Hood’s house there’s an advertisement on TV that goes ''[[VideoGame/{{Persona 4}} Everyday's great at your Junes!]]''
* In one optional dialogue with Dreisan, Phoenix mentions Marvin Grossberg being murdered at Verglas Bridge, which suggests that this game may take place in a SharedUniverse with ''[[VideoGame/PhoenixWrightAceAttorneyTheContemptOfCourt The Contempt of Court]]''.
** Dreisan also once mistook Phoenix's name as Cicatrice, a lawyer there.
* Another one involving Dreisan: During the part where you [[spoiler: investigate as Trucy]], she and Dreisan have this exchange:
-->'''Dreisan:''' Say, aren't you a bit young to be investigating murders?
-->'''[[spoiler: Trucy]]: '''[[WesternAnimation/PhineasandFerb Yes. Yes, I am.]]
* Towards the end of the final case, Watters attempts to stop [[spoiler:Luciano]] from escaping and ends up getting stabbed in the knee for his troubles. After the trial, he meets up with the gang, causing Trucy to ask about his stabbing to which Watters replies that it's "[[Film/MontyPythonAndTheHolyGrail only a flesh wound]]," before collapsing from it.
** Later, in the credits, Watters tells the player that he plans to tell new recruits about his scarring while he's on desk duty recovering: "I used to be a hotshot detective like you, [[VideoGame/TheElderScrollsVSkyrim but then I took a knife to the]]-" Unfortunately, the Chief yells at him to get back to work on his physical therapy before Watters can complete the meme.
* In a previous version of the game, two of the known victims listed in the Sir Gallante case files were [[Anime/PokemonTheSeries James Rocket and Jessica Rocket.]] In the current version, two of the victims are named [[Film/TheGodfather Vito Rivales]] and [[Creator/MarlonBrando Marlon Rivales]].
* In Turnabout Consequences, [[spoiler:Pearl's attempted suicide report]] mentions that she was admitted to [[VideoGame/TraumaCenter Resurgam First Care]].
* When you present Maya's profile to Cody in case 3, she will mention substituting Phoenix in court once, referencing fellow fangame Trials after Justice.
