The illustrious Ms. Stewart (better known to psychotic Twihards as Bella Swan) had never particularly impressed me. I'd seen her in a couple of things and she'd seemed to have a rather harsh quality to her. Plus, she's gotten a shit-ton of negative press over a less than grateful/gushing attitude about Twilight and its ravenous fans.
So, in short, I fully expected her to be a bitch. I am pleased (for her) to announce that she was not. She wasn't bursting with Disney goodness and offering to bake us cookies or anything--far from it. She was smart, intense, and a little nervous--saying that she'd heard us all laughing before she came in when we were doing the previous round of interviews and was worrying that they'd be a tough act to follow (and she seemed to actually mean it). She was clearly physically tense--kind of caved in on herself, and shaking her leg the whole time.
BUT, and this is a big but, she actually laughed once or twice and when we asked a couple of obligatory Twilight questions she didn't tell us into which orifice we could shove them. That is what surprised me. She was actually, weirdly, almost better able to answer those questions than the ones about the movie she just did because she's obviously a little humble about her work and doesn't like to sit there and be like, 'Oh I am so amazing, yes I am very talented,' which is also nice.
Her costar, btw, Aaron Stanford, whom I hadn't really seen before (evidently he was Pyro in X-Men, amongst other things) was a really easy going and funny, nice guy. She obviously was very comfortable with him, and I think he went a bit of a way to chill her out.
I guess the bottom line is this: Kristen Stewart is a bit of a serious, intense, Daria type.She can come across as a little prickly or defensive, but I got the impression that there was the hope that that covered a thoughtful person instead of a self-important bitch. After all, she is just a 19-year-old dealing with insane fan and press attention, and that is enough to scare the bajeesus out of anyone. But in person, at least when I met her, she may not have been a teddy bear, but it wasn't the diva-tude I expected. Two points for Missy K.
