* ActorAllusion:
** By proxy. In ''Office Christmas Party'' she's seen reading ''Literature/TheGirlOnTheTrain''. Her husband Justin Theroux played Tom in the film adaptation of the book. The same film also has a line where her character is said to be "salad and Smart Water"; Jennifer is a spokeswoman for Smart Water in real life.
** In the ''Friends'' episode with Monica and Chandler's wedding, Rachel finds a Greek Orthodox priest coming out of the Anastassakis/Papasifakis wedding. Anastassakis is her father's real surname.
* AwesomeDearBoy: She did ''Film/AlongCamePolly'' so she could dance the salsa.
* BeautyInversion:
** ''Film/TheGoodGirl'' has her wearing baggy clothes, MessyHair and a generally unfashionable appearance. Her character also cheats on her husband and is [[GoodAdulteryBadAdultery not portrayed as justified in doing so]].
** ''Film/Cake2014'' gives her a scar on her chin and another on her legs. She wears no make-up for most of the film, and is seen mostly in dressing gowns and pyjamas.
* CastingGag: Rachel's best friend Mindy, who stole her fiancee, is played by Jennifer Grey. Both actresses had played Jeannie Bueller - Grey in ''Film/FerrisBuellersDayOff'' and Aniston in the attempted spin-off TV series.
* CelebrityVoiceActor:
** As Annie Hughes in ''WesternAnimation/TheIronGiant''.
** As Galatea in ''{{Disney/Hercules}}'''s TV spin-off.
* TheDanza: Almost. In ''Film/OfficeSpace'' she played Joanna, which is her middle name.
* DyeHard: While she's recognized for her honey blonde hair, [[http://web.archive.org/web/20180315231653/https://www.usmagazine.com/stylish/news/jennifer-aniston-is-jealous-of-kate-middletons-hair-2013136/ she actually has]] "naturally wavy, frizzy Greek hair." Look no further than [[http://cdn1.alloy.com/wp-content/uploads/2011/09/chaz-jen.jpg this picture]] of her with Chaz Bono in their senior year of high school. She kept her natural dark brown hair earlier in her career prior to ''Series/{{Friends}}'', but since the show she's gone through most of the shades of blonde.
* DyeingForYourArt: Subverted in ''{{Film/Leprechaun}}''. The studio wanted her to bleach her hair blonde, but the director had her keep it in her natural dark brown.
* EnforcedMethodActing: For ''Film/TheGoodGirl'', she wore wrist weights so as to look more worn down.
* HollywoodHypeMachine: The book ''Desperate Networks'' (about how TV worked during the mid '90s through the 2000s) goes into some detail about how she was a "network darling", and the studio was actively looking to give her a break-out role. The Hype Machine got behind her ''big-time'', showcasing her constantly in all forms of media. She is actually given far more mainstream press than her non-A-list movie career would warrant, except for the fact that she's wildly famous regardless of her films' success, and she ''sells'' magazines very well.
* IAmNotLeonardNimoy: Particularly in the 2000s where all her roles evoked the same public image of her as this fun-loving, fashionable party girl. She was even turned down for ''Series/TwentyFour'' because of this. But she did manage to avoid this in ''Film/HorribleBosses'' and ''Film/Cake2014''.
* OldShame:
** ''{{Film/Leprechaun}}''. Jennifer recalls being proud of the film when she first got it, as it was her first studio picture and she was starring alongside Warwick Davis. Then she became famous for ''Friends'' and ashamed of the movie. She does poke fun at it though.
** The famous Rachel hairdo she sported in the first two seasons of ''Friends''. She hated the cut, didn't understand the fascination with it, and grew it back at once.
* PlayingAgainstType:
** She plays TheVamp in ''Derailed''.
** A cynical stripper in ''Film/WereTheMillers''.
** An evil nymphomaniac in ''Film/HorribleBosses''.
** A depressed checkout worker in ''Film/TheGoodGirl''.
** A chronic pain sufferer in ''Film/Cake2014''.
* RealLifeWritesThePlot: Jennifer and Creator/ReeseWitherspoon allegedly didn't get on while filming ''Friends'', so Jill was written out and a new sister Amy--played by Christina Applegate--was used.
* RomanceOnTheSet:
** She dated Vince Vaughn while they were both starring in ''The Break-Up'' together.
** Inverted. She had split up from her engagement with Tate Donovan right before he starred as her boyfriend on ''Friends''.
* StarMakingRole: Rachel Green in ''{{Series/Friends}}'' turned her into a superstar.
* ThoseTwoActors: Jason Sudekis has starred with her in ''Film/WereTheMillers'', ''The Bounty Hunter'', ''Mother's Day'' and both ''Film/HorribleBosses'' films.
* ThrowItIn: The white dog in Joey and Chandler's apartment was a gift someone had bought her when she started acting. She brought it to the set for the day, and producers liked it so much they kept using it.
* TomHanksSyndrome: She has flirted with this a couple of times, straying into dramatic roles in ''Film/TheGoodGirl'' and ''Film/Cake2014''.
* TypeCasting: With the popularity of ''Friends'' she was put in lots of romantic comedies where she usually played the ManicPixieDreamGirl or other roles that evoked Rachel Green in some way.
* WhatCouldHaveBeen: Which might explain why she auditioned for the role of [[Series/{{NCIS}} Special Agent Caitlin Todd]] and even asked TPTB to hold off on starting the show until she was available[[note]]NCIS premiered in 2003, the year Series/{{Friends}} began its last season[[/note]].
