Mischa Barton hasn't had the best luck getting roles lately, but we'll always remember her as the stunning Marissa Cooper on The OC!

Last night the 36-year-old 26-year-old starlet attended Domingo Zapata's Oscar Art Show in Beverly Hills (yes, this is the same event Lindsay Lohan went to) and since we last saw her, it appears as though her hair has gone from blonde to washed-out auburn. Not her best look, but perhaps it's for her part in I Will Follow You Into the Dark, which she's currently shooting?

The film follows Sophia (Mischa's character) and her romance with a man named Adam (played by 90210 hottie Ryan Eggold). According to IMDb, "After Adam disappears mysteriously into the depths of a haunted apartment building, Sophia vows to pursue him, even if it means walking over the threshold into the realm of death." Sounds ... amazing.
