Collider.com has a few new behind the scenes clips from the film.
There's a few (bigger?) spoilers in these too, so if you're one of those people who want to be surprised, I wouldn't watch.
I can't embed the clips so go here
Clips with interviews featuring Robert, Kristen and Stephenie can also be viewed here
Thanks to musicmind314 for finding these.
The first clip is apparently the Penelope DVD scene...
