One scene is glimpsed in the teaser trailer, below.

Its really sad, Ridley says.

And its going to be really sad.

The scene was me being very sad, she says.

Lets just say it was not hard to be upset in that scene …

I did this embarrassing speech that I cant remember.

It was so sad.

Then I remembered we had these scenes that we hadnt used fromEpisode VII.

It was like finding this impossible answer to this impossible question.

Suddenly we had classic Carrie in these amazing moments.

So when you see in the movie, its her, shes there.

Its not like theres some crazy digital trickery.

Shes just in the movie.
