'There’s nowhere to go with it': Mischa Barton wows in plunging crimson gown as she shoots down a reunion for The O.C. 

She looked downright radiant, right up until she was asked about the pop culture-defining show that launched her career.

Mischa Barton, 29, dressed to impress Thursday at a Toronto International Film Festival gala, and definitely had an opinion when asked whether she would want to be a part of a The O.C. reunion show.

During an ET interview, the starlet laughed dismissively and responded 'No. I mean I just doubt very much', when asked if she would want to participate in such a throwback project.

Aside from the career questions, Mischa showed she could still draw attention, donning a long, flowing crimson gown for the event.

The form hugging number evoked old Hollywood glamour, while spicing it up with a plunging V-neckline that readily showed off the star's decolletage.

Her famous flaxen locks stuck to the classic theme, as she opted for a flattering shoulder-length bob clipped back behind one ear.

So that's a no: During the interview the starlet laughed dismissively and responded 'No. I mean I just doubt very much', when asked if she would want to participate in a reunion show for The O.C.

The former O.C. star accessorized with a small red purse studded with gold accents and a thin, gold corded shoulder strap.

She completed the look with some slightly darker crimson lipstick that perfectly set off her porcelain skin.

When asked to delve into more detail as to why she didn't think a reunion show was in the cards, the some time television icon was more than happy to oblige.

'I just think that those characters, they had a life of their own and they burned out very fast because they were just fascinating.'

Interestingly, though the foxy soap opera catapulted Mischa to the heights of fame, she revealed in a 2014 interview with Metro U.K. that she was somewhat wary about doing the show in the first place. 

'It's something I came so close to not doing,' she said, before adding 'people say be grateful for what you have but it's certainly not the kind of thing I was expecting it to be.'

Her focus now lies with developing new TV projects, as well as acting in independent films, such as the indie drama Father, slated for release on January 1st.
