Tracey Heggins and Judith Shakoni, who play South American vampires Senna and Zafrina, shared a moment with Renesmee. "It's just so fun to play in this magical land [of Twilight]," Heggins has said. "You know, science fiction is amazing. . .They were so welcoming, but it's a machine. The fans are so dedicated, just to be able to have people rooting for you before they even see you, it's exciting."
