Actor Amy Adams has said that she needs to know the background of a character before she can embody it on screen. According to Femalefirst, the "Arrival" star said that it adds to her performance if she can give her character a good back story.

"For each character, I build a psychological back story from the age of around three - I'll imagine their whole life leading up to the present day," Adams said. Adams most recently starred in HBO series "Sharp Objects" where she played Camille Preaker, an emotionally troubled reporter who returns to her hometown to cover the murders of two young girls.
