He mentions Kristen at 4:22 He says Kristen was most upset about finishing filming Breaking Dawn. Awwwwww
He went on to explain that while the core group of Twilight stars will continue to promote Breaking Dawn's two-part release for years to come, wrapping up filming for The Twilight Saga for good did get a bit emotional.
"It’s very weird. Yeah, we’ve literally been filming these movies for the past three or four years. It’s strange to know I’m not going back; I’m not going to be Jacob Black anymore . . . but on the other hand, we’re going to be promoting these movies for the next two years . . . I was pretty upset myself, but I think the biggest surprise was Kristen. She’s very sweet, yes. I predicted it from the beginning . . . on the last day, it did get emotional." Tears were shed, he admitted.
