While on set we had the opportunity to meet many people. It takes a great deal of talent to make a movie possible. From the doubles/stand-ins, to the sound, to the lighting, to the props and transportation. Every person on set is vital to the filming process. Here are a few Twilight movie doubles we met on our journey. Without them, shooting this film would have been very difficult. We present our salute to the Twilight Movie Double…
The person behind Katie in the opening interview is actually physically holding the tent down.
"What does a double do exactly?" I am glad you asked. A double stands in place of an actor during lighting and scene staging. They do not do stunts. Thats what stunt doubles are for. Doubles are often used in scenes where the actors face is never seen. For instance in wide shots. Doubles allow film makers the freedom to experiment with scenes without having to use the "talent" for non speaking, non acting situations. Particularly with underage actors doubles become EXTREMELY important because the actor can only spend so much time on set. So they have to use them judiciously. And in the case of Twilight, the underage actors on set are great in number, which included Kristen up until a month ago.
I hope this answers your question! *goes to rock out to Eminem some more*
