Cake (2014) 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.
Casting Gag: Rachel's best friend Mindy, who stole her fiancee, is played by Jennifer Grey. Both actresses had played Jeannie Bueller - Grey in Ferris Bueller's Day Off and Aniston in the attempted spin-off TV series.
She dyed her hair a dark brown for Horrible Bosses, 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.
Hollywood Hype Machine: 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.
I Am Not Leonard Nimoy: 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 24 because of this. But she did manage to avoid this in Horrible Bosses and Cake (2014).
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.
