Break the Haughty: While not to the same extent as Ludlow, Sarah seems to think she can handle in a dinosaur-infested island herself despite the warnings of her boyfriend who she thinks is a worrywart.
Being played by Julianne Moore she is gorgeous but while the character is supposedly brilliant she carries the Idiot Ball so firmly her actions would have been identical had she been deliberately portrayed as an airhead.
Brainless Beauty: A bizarre unintentional example.
The novel's version is probably one of the most badass characters in the franchise, surviving being thrown into the water on the way to Isla Sorna, and later feeding the person who threw her to the T.
Adaptational Wimp: A highly noticeable example.
Adaptation Dye-Job: Has short black hair in the novel.
In the novel, she's notably muscular, but not in the film.
Action Survivor: She can't fight at all, but she somehow survives all the horror in the film.
