First of all, about the above scene from the Penelope DVD which I have now watched 10 times, OME!! I love the passion that you can feel between them when they are doing something as simple as listening to music, how they slowly move towards eachother and no one really making a bold move, both being a little timid but clearly both WANTING to be close, to touch. Just coming to a very gentle closeness, like you can feel that Edward still feels that Bella is so fragile and precious to him. Amazing, amazing chemistry! I mean at this point I don't think they're physical actions portray how deeply in love with eachother there are at this point, like PDA wise, but the emotion, the facial expressions the mannerisms make the scene say so much more than if they just walked in the room and started making out! Don't you think?
And I found this clip compiled of Rob Kristen interview
It is very aptly entitled "Interview Moments That Make the Fan Girls Squee" http://www.youtube.com/watch?v=VMxoPMp-2GA&feature=related
After seeing thier off screen chemistry on that and all the time the spend together when they're not necessarily working, I'm sure it easy for them to be great friends if not something more!!! In fact if I was Kristen, with as charming as he is to her and all the steamy movie scenes, I would be developing myself a big old crush on Mr Pattz there.... haha!
