Conlon died of lung cancer on Wednesday morning at her home in Fort Bragg, Calif., her friend, Bruce Lewis, said. Her son, Matthew Ned Conlon was by her side.

At age 4, Conlon was cast to play the small, but pivotal role of Bonnie Blue Bluter in the1939 film. Her character's death in a fall from a pony irrevocably damages Rhett and Scarlet's tumultuous marriage. She earned $1,000 for her few scenes.

Conlon also voiced the young doe Faline in Walt Disney's "Bambi" three years later. It would be her final film role. "I was washed up at 5," she said in an interview last November with The Press Democrat in Santa Rosa, Calif.

Lewis says she never stopped gamely reprising her Bonnie Blue days for "Gone With The Wine" enthusiasts. Last year, she self-published a book, "Bonnie Blue Butler: A Gone With The Wind Memoir."
