10 Actors Who Spoiled Huge TV Deaths

10. Mischa Barton - The O.C.

The O.C.'s third season concluded with the shocking death of one of the teen drama series' main characters, Marissa Cooper (Mischa Barton), who is involved in a serious car accident and subsequently succumbs to her injuries in sometimes-boyfriend Ryan's (Ben McKenzie) arms.

Well, it would have been shocking had Barton not spilled the beans literally hours before the episode premiered in the U.S. 

Barton was interviewed by Access Hollywood the day before the scene was due to air, where she flat-out said, "It’s true, it’s true. My character dies... My character has been through so, so much and there's really nothing more left for her to do."

And so, while Barton's potential departure from the show had been whispered about for months - due to the actress apparently wishing to pursue film opportunities - ruining the surprise so close to go-time naturally left many of The O.C.'s hormone-addled fans absolutely baffled.

Then again, considering how divisive Marissa's death was among the fandom, perhaps this was a merciful case of giving them a little heads-up.
