The OC Fans Furious at Mischa Barton  5/19/06

Fans of teen drama The OC are furious with star Mischa Barton for revealing her character, Marissa Cooper, dies in the show's season finale - before it even airs.

The actress sat down for an interview with entertainment news show Access Hollywood, which is set to air hours before the show's final episode tonight (18MAY06).

Media reports suggested the star's character could be leaving, but the show's producers have tried to keep the ending top secret, filming multiple conclusions with different cast members being killed.

Access Hollywood sent out an email promoting tonight's interview with the star, setting off a string of media reports revealing the secret ending.

The email alert featured the subject line "On the next Access Hollywood:

Mischa Barton Confirms Her Character On The OC Dies and Reveals What the Show Has in Store For Fans."

The 20-year-old actress had expressed a desire to leave the show to focus on her film career.
