I know, I'm a dork and follow the cast and director's tweets from the Eclipse set. Peter Facinelli tweeted today:
Fast at work. Literally. Running through the woods all day today.

Hmmm....this must be the scene in Eclipse when they are gathering in the woods for the meadow showdown with Victoria and her newborn vamps. Eclipse is my absolute favorite book in the series, so I'm a bit more invested in the making of this movie!
