Yes, the Twilight trio have appeared in a behind-the-scenes video that previews the first part of the finale.

Most enlightening is Stewart's chat about her character's state of mind leading up to the wedding.

“There are few beats right before the wedding actually occurs that really send [ Bella ] into the anxiety that she brings into the ceremony, when she first starts walking down the aisle," Stewart told Entertainment Tonight . "There are a few looks from Edward that are just kind of unclear to her.”

After the stars get serious about their roles there's also some B-roll footage and on-set laughter that make this worth a peek.
