No matter what kind of day you're having, Marissa Cooper's having a worse one. Mischa Barton's The O.C. character went through the ringer during the first three seasons of the teen drama (remember how she overdosed in Tijuana...and also saw her parents post-hookup after their divorce?).
And during her time on The O.C., Mischa Barton struggled with drug and alcohol abuse. She was arrested for a DUI in 2007 and eventually received involuntary psychiatric hospitalization in 2009 after allegedly threatening to end her own life. And in a new interview, Peter Gallagher (who played Sandy Cohen on the show) says he's "just so grateful" for "the fact that she’s still alive."

The O.C. follows Ryan Atwood, who moves in with the Cohens after getting kicked out of his mom's house, and starts a relationship with Marissa shortly after. While Peter Gallagher played Adam Brody's TV dad instead of Mischa's, Sandy was a definitely father figure for Marissa, and it seems like Peter felt that same responsibility off camera.
"I’ve always felt very protective of her," Peter told The Independent. "First fame is toxic. First fame can kill you. She was 16 years old when she started working with us, so just the fact that she’s still alive, I’m just so grateful."
“You can go to therapy every day for the rest of your life,” Mischa said in a 2023 interview with The Sunday Times. “There’s just a certain amount of trauma [from] all that I went through, particularly in my early twenties, that just doesn’t go away overnight.”
Josh Schwartz and Stephanie Savage revealed that season 1 overdose not only served as a cliffhanger, but gave “network executives an escape hatch on a performer they had been wary about” (via People). But Mischa Barton got her big break, becoming "how people knew the show," and (thankfully) Marissa recovered — only to die after a car crash in season 3.
As hard as that season 3 ending is to watch, Mischa did have the opportunity to watch it with Rachel Bilson and Melinda Clarke for the first time on their rewatch podcast. "It needed to be a thing, after everything she's been through, but if it's here I'll watch it with you," Mischa says.
"I couldn't do it, Mischa, I couldn't do it," Rachel adds. "But I'm going to do it if you're going to do it."
Mischa says even though being written off the show "was a little bit of a bummer," it wasn't necessarily a surprise. "The character was just doing too much," she told Vanity Fairin 2023. "And I think they ran out of places for her to go. It was not the best thing in the world, [but] there wasn’t much you could do at that point. It was whether she could sail off into the sunset, or die. At that point, I guess it’s better to have the more dramatic ending.”
