Emma Watson is another one (who survived). Prior to Shields, there was Oliva Hussey, Tatum O'Neill and Jodie Foster. But the weirdest and saddest case was Anissa Jones, who played "Buffy" on Family Affair. She was eight when the show started, 14 when it ended, yet her contract stipulated that she was always eight years old and when she was on any show, it was always 'in character.' Her 'twin' brother, played by Johnny Whitaker, had facial hair in the last season (nine/16). She overdosed at 18.
