Natalie Peri has a photographic memory, which allows her to read, for the first time, a screenplay just 30 minutes to an hour before filming and deliver her lines perfectly. She can read a screenplay overnight and memorize her scenes so well that she not only knows all her lines but can help other actors with their lines as well.
Some people have compared Natalie Peri to Marilyn Monroe, probably because of her seemingly overnight popularity and fandom that has appeared almost magically.
