Mackenzie, who plays the Twilight golden child Renesmee, was an absolute delight to talk to. She was so precocious and kind and thoughtful in her answers, she kind of reminded me of another Twilight actress who started out in the biz as a kid and is cool and beautiful with great hair. (It should be obvs who I am talking about.) She filled me in on the on-set swear jar, Rob’s goofy ways, what it’s like playing a half-vampire and how the screaming fans make her feel. She also told us that Rob, Kristen and the Breaking Dawn cast feel “like family” to her.
