None of the movie's stars are allowed to take the scripts home at the end of the day as Summit Entertainment tries to keep their movie adaptation of the book by Stephenie Meyer a secret until it is seen on screen.
According to US website Hollywood Life, those who auditioned for Breaking Dawn were asked to read from the previous Twilight scripts and they never saw the new script until they landed a part.
Pattinson, 24, and Stewart, 21, were reportedly not allowed to see the Breaking Dawn script until they were on set and nobody is allowed to leave the set until each script is accounted for.
