"Well, the wedding scene was like a real wedding, in that it was stressful," Elizabeth Reaser, who plays Esme Cullen, explained to MTV News. "It took a lot of planning, a lot of organization. That was stuff we were all dealing with and it was like you were planning a real wedding."

But the ceremony was so beautiful, Elizabeth had to try not to cry!

"But it was really magical, and vampires aren't supposed to cry, and that created a real obstacle for all of us vampires," she said.

As for Rob and Kristen, having to pretend to marry each other created real nerve for the real-life couple.

"Seeing Kristen walk down with aisle with her movie dad Billy Burke. I mean, seeing Billy Burke killed me. I understood in that moment what it's like to be a parent, and seeing Kristen and see her really be nervous and see Rob really, really be nervous, and the two of them together with the families coming together; it was an emotional day for real."
