Mischa Barton

The O.C. captured the imagination of a generation in the 2000s. At a certain point, Barton grew tired of her role of Marissa Cooper and believed there were greener pastures outside of the show.

Her character was killed in a devastating car accident, even though writers would’ve preferred Marissa to just move to another town. Barton fought to stay true to her character, explaining that her character could never be satisfied with ending anything so low-key. Fans went through a collective heap of tissues watching her death.
