Mischa Barton’s stardom outpaced her genuine character.
Mischa Barton was one of those persons who lacked the maturity to deal with her sudden popularity. Actress Mischa Barton got famous after starring in the teen drama The O.C. Her co-actor Tate Donovan had previously described her as cocky and diva-like because of her inflated sense of self-importance when she became a star. It was even suggested that she used drugs. From these accounts alone, it is easy to see why nobody wants to work with Barton.
