The Original: Bella and Edward go for a flit through the woods, with him leaping from tree to tree and her breathless on his back.

They end up at a wooded glade, whereupon Bella truly discovers what Edward is and that, unlike the stinky usual vampires, he doesn’t burst into flame in sunlight, he just glitters like a gemstone.
 
JC Comment: “This scene is nowhere near groundbreaking enough!”

The James Cameron Version: Bella and Edward are in the trees.

Suddenly, for no apparent reason, Edward starts banging on about how important the massive oaks are, and how we should look after nature and how, really, when you think about it, human beings are the real monsters.

Realising he’s boring Bella, Edward decides to impress her by running really fast through the trees like a Na’vi might. The shot cuts to a first person perspective view of Edward jumping from branch to branch really quickly.

This scene all happens in fully immersive 3D, which makes you feel like you’re watching a dream. The sort of dream you don’t really remember when you wake up.

Edward and Bella are replaced by CGI versions of themselves, but no-one notices because that’s how good the special effects are.
