Richard Sherman gave an interview to Architectural Digest, in which he describes the sets of Breaking Dawn, and how each contributed to the film. He also shared a few personal comments about Rob and his costars:
RS: Everyone had a good time. The three main actors are all very fun to work with. Kristen is quite serious. Rob and Taylor are a little bit wild. Rob and Kristen are actually a couple in real life. When he’s with her, he’s a little more restrained. When she’s not around, like most guys when their wives or girlfriends aren’t around, he’s a little looser. Taylor’s a kid—he’s 19—so he was bouncing all over the place.
