Cammie King Conlon, the former child actress who portrayed the doomed daughter of Rhett Butler and Scarlett O'Hara in the movie "Gone With the Wind," has died at the age of 76. She died of lung cancer Wednesday morning at her Fort Bragg home on California's north coast, the Associated Press reported.

Conlon, who was cast in the role of Bonnie Blue Butler at age 4, also voiced the young doe Faline in Walt Disney's "Bambi" three years later. That was the end of her Hollywood career. "My mother decided she wanted me to have a normal childhood," she wrote on her blog. She often joked with interviewers that she had "peaked at 5."

But she will always be remembered as a key character in what may be the most impressive movie adaptation in history -- bringing Margaret Mitchell's novel to millions of fans.
