there is a thing called make-up

agreed^ look at the HP movies!

i'm more worried about the grow-up-thing with renesmee

Yes but by the way they are heading at Summit, they may not be too old. Breaking Dawn could be out in late 2010 or early-mid 2011.
But yea, I'm worried about Renesmee too!

Yes, Renesmee will be hard to do but it would be rubbish if they did the first three films and not the last one. It's the best one!

The only thing I want is to have the book split into two movies. Up until Bella gives birth to Renesmee and then has to be turned by Edward as part 1, and the rest of the book after as part 2.

by the time breaking dawn comes out they'll have plenty of new technology to make renesmee as good as they can. she won't be perfect, of course. everyone sees her differently.

As long as they don't change any of the cast from Twilight i'm happy! Who cares if they are older that's what makeup is for.
