* 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.
* TheDanza: Almost. In ''Film/OfficeSpace'' she played Joanna, which is her middle name.
* DyeingForYourArt:
** She dyed her hair a dark brown for ''Film/HorribleBosses'', even fighting the studio to let her do so, as producers feared she wouldn't be instantly recognizable in the promotional spots.
** Subverted in ''Leprechaun''. The studio wanted her to bleach her hair blonde, but the director had her keep it brown.
* 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 it. She does poke fun at it though.
** The famous Rachel hairdo she sported in the second season 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''.
* RomanceOnTheSet: She dated Vince Vaughn while they were both starring in ''The Break-Up'' together.
* StarMakingRole: Rachel Green in ''{{Series/Friends}}'' turned her into a superstar.
* 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.
