was never as terrified of a role as she was for her latest part in "Grey Gardens."
The television movie, which debuts tonight on HBO, stars the 34-year-old Barrymore asEdith "Little Edie" Bouvier Beale
, who lived a reclusive life of wealth and extreme poverty before her death in 2002.
To take on the role, Barrymore, who made her name as the child in "E.T.: The Extra-Terrestrial" in 1982, had to age herself with makeup and costumes from a college-age ingenue to an elderly woman, and she had to master the accent of upper-crust New York society. She says she had to campaign for the role, which only added to the stress when it came time to perform.
"This had a challenge in every freakin' corner, it was terrifying," Barrymore told Reuters. "But I just fell in love with her, who she was and who she became."

Mother and daughter took up residence in their sprawling manor, Grey Gardens, on Long Island, New York and as the years went by they lived on a smaller allowance from Phelan Beale.
The house fell into disrepair, and was overrun by cats and rodents. It became such a nuisance that local officials threatened to raze the mansion until Jackie O stepped-in to aid her cousin and aunt.
ventured out to Long Island in the early 1970s and made a documentary movie about the Beales called "Grey Gardens."
Over the years, it developed a cult following and "Little Edie" mushroomed into a heroine of sorts because, despite her odd and reclusive life, she maintained a sense of style that had her singing in nightclubs after her mother died.
"She is a really fascinating person," Barrymore said. "She's tortured. She's on an emotional seesaw all the time -- one minute she's happy and dancing around and entertaining, and the next minute, she's full of sadness and heartache."
Among the challenges, Barrymore said, was adopting the accent of a New York society woman. She worked with a voice coach for one year to perfect the tones and language.
To reach middle-age years and beyond -- make her body look both thin and thick -- Barrymore sat in makeup chairs from four to six hours at a stretch and used 13 prosthetic devices. She said she became a bit of a recluse herself, cutting ties with friends while she wore the face and clothes of "Little Edie."
"I was so fraught with fear," the "Charlie's Angels" star said. "I couldn't eat or function and felt I was totally losing my mind," she said.
But judging by early reviews, her work seems to have paid off. Rolling Stones criticPeter Travers Jessica Lange
