Actress Amy Adams gives all her characters a back story from the age of three to help with her preparations."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 told Psychologies magazine.Adams has moved from movies to the small screen with new eight-part drama series "Sharp Objects" and part of playing the role of investigative reporter Camille Preaker, who has recently been discharged from a psychiatric hospital.It made her "uncomfortable" so she was thankful for the support of her family and friends in helping to put the role behind her at the end of a day's filming, reports femalefirst.co.uk."You have to go and live in a place that's rather uncomfortable, but I am lucky that I have great friends and family and they pull you right out at the end of the day.It was darker and deeper than I first thought though," she said.
