Hellloooo, diva!!! Kirsten Dunst recently banned someone from the set of her movie How To Lost Friends And Alienate People, and that person happens to be the author of the book the movie is based on.
Toby Young visited set one day and made a comment on Dunst's performance to the director Bob Weide. He says, "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 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 realize it, but this was, in effect, Bob carrying out Kirsten's instructions."
Looks like someone thinks they're too good for some constructive criticism! We'll have to see her performance when the movie comes out and make an assessment of our own.
