Twilight Sagascribe Melissa Rosenberg should consider dabbling in espionage.

ends up being nothing but a vision of a possible future.

Of course, theres a little more to it than that.

Bd2 Battle 02

Heres the tale ofBreaking Dawn Part 2s shocking battle scene, from conception to screen.

For more stories behind this years top moments, clickhere for TVand here for movies.

Stephenie knew the book ended with this really tense conversation, and she knew that that wasnt cinematic.

We just went back and forth and were like, Thats it!

Thats gonna work!

The way I approached it was, who would be the most shocking to kill?

Because the first death initiates the battle, it has to be someone who everybody cares about.

And because theyre all there for Carlisle, it made sense that he was the one.

Well, actually, the first one who is killed in reality is Irina.

But the whole company doesnt actually know her Carlisle, theyll go to battle for.

And you also want, like, whos going to be the most satisfying to kill?

Who have been the various nemeses?

So everyone kind of gets a moment.

Of course, Bella and Edward had to be the ones to kill Aro.

That was the ultimate, and that they do it together felt really right.

I really wanted to see Bella just rip his frickin head off.

[Laughs]

The gloves were off [inBreaking Dawn: Part 2].

They played it very comedically.

When you have Bella turn into a vampire, you get humor.

And its less about the tortures of love and more about kicking some butt.

I dont think theres anything in there that actually does deviate from the book.

Stephenie cant write that scene because Bellas not there.

But I get to write it!

[Laughs]That is so much fun for me.

And at the premiere, it was just the screaming just went on and on.

Every time someone would die, people were just screaming, Oh my God!

And then when they realized what the truth of it was, they screamed all the more.

It was so funny.

[Laughs]And Im like, Shut up, that was a really funny line right there!

You just missed it!
