My theory behind Super-Hermione, and will Ginny be able to convince us?

So, this might have been discussed already (it probably has) but being 
that I am still relatively new around here, and there are a lot of 
newer people who might like to discuss this, I thought I'd bring it up.
(It's actually on my mind because HBO has been playing PoA quite often 
recently, and I can't bear to let a HP movie go on without watching 
it!!)

I wonder if the reason the movies tend to portray Harry & Hermione as 
very affectionate (more affectionate than thought for friends of age 
13) is because the director(s) are just utilizing the actors natural 
chemistry to their advantage.  I think I've read that Dan and Emma are 
pretty good friends off-screen (and some speculations that they are 
more than just friends).  Plus Emma's actual real-life personality 
seems to come very much into play- she is bubbly, and (when I've seen 
in a few interviews) she sort of takes over a little bit.  Or 
sometimes Emma and Dan seem to be battling for the spotlight, but then 
Dan seems to eventually concede to her.  

Rupert, who is seemingly more shy and self-effacing, just doesn't 
seem "the type" to be a born leader.  If he is, he's reluctant about 
it and that's why they have his character act the way hes does (the 
wizard chess scene in SS).  It's like (for the trio, anyway) the parts 
are written for them, not necessarily what JKR wrote for them in her 
books.

And, I wonder what this would mean if the relationships changed 
between these actors?  What if Dan and Emma got into a fight and hated 
each other?  I think things would change.  I also wonder if Bonnie 
(the actor who plays Ginny) will be able to be a convincing enough 
actress to play Harry's love interest?  OoTP is kinda where things 
get "started" between the two.  Any thoughts?
