I wasn’t surprised when I read that actress Helen Hunt recently stated that she would never allow her young daughter to become a child star. Ms Hunt is the daughter of a Hollywood technical director, and grew up in Hollywood. Now in her late 40s, she started acting and modeling when she was eight and has probably seen a lot over those years in show business.

She has had a successful career. She earned four Golden Globes and four Emmys. She also attained the top honor of her profession when she won the Best Actress Academy Award for her role in the 1992 movie, As Good As It Gets. Given those accolades, Ms Hunt is successful. There is no doubt that her early experiences as a child star prepared her for what has been an outstanding adult career. Given those achievements, why would this star declare she’ll never allow her daughter, now at the age of six, to follow in her footsteps?

Everyone familiar with the entertainment scene is aware of the reasons for her attitude. Recent tabloid (小报) news headlines featuring the troubles of former child stars, among them Lindsay Lohan, Britney Spears and the late Gary Coleman, may answer the question. Although Ms Hunt managed to become a successful grown-up star, she apparently believes she’s an exception.

What Ms Hunt may be suggesting is that many very young stars go through unnatural childhoods on movie and TV sets. While they’re earning big incomes, they’re so pampered (纵容) by directors and praised by fans; they may get false impressions that their lives will always be that way. Then, within a few years, when faced with reality, they’re hurt and confused. After all the overwhelming affection, they find they can’t deal with the problems. That’s often when drugs and alcohol take over their lives.

Helen Hunt has some other reasons why she doesn’t want her daughter to be in the entertainment business. Many child stars can never make a successful transition to meaningful adulthood. However, as with many Hollywood movies, I believe there are both good and bad scenes about how it can be played out in real life.
