I love reading 'behind-the-scenes' stories like these! Who would have known that Kirsten was this type unless someone had enough guts to take it to the press ?

Kirsten Dunst banned a writer from the set of her new movie after he allegedly criticized her acting ability. British novelist Toby Young wrote the book on which the actress’s new film How to Lose Friends & Alienate People - is based, and visited the set on several occasions. And on his second visit, Young made comments regarding Dunst’s performance to a producer - and it led to the actress asking movie bosses to bar him from the studio.

"She overheard me giving the producer a "note" on her performance in a particular scene. At the time, I didn’t think of it as a criticism, more as a helpful bit of advice, and the producer took it in that spirit.

"But Kirsten overheard this exchange and interpreted it as a complaint about her acting ability. It was after this, apparently, that she took Bob (Weide, the director) to one side and asked if I could be kept at arm' s length in future. "Bob carried out this edict with a good deal of tact. I didn’t realise it, but this was, in effect, Bob carrying out Kirsten's instructions."

Guess Kirsten didn't like someone telling her to change her method. Can you imagine if you were the writer and you were told you weren't allowed to go on set?
