So that means a great deal of children's' television can't be made. No Tracy Beaker, no Goodnight Mr Tom, no Grange Hill or Byker Grove.
Nor films of course, so no Harry Potter series (Emma Watson and Daniel Radcliffe have matured into thoughtful, talented young adults but hey), no Narnia films.
And no characters in tv or film can have children, or they'll all have to 'stay in their room' until they are 16.
And no Charlotte Church of course - wasn't she nine or ten on her first TV appearance?
Hollywood is a very, very dysfunctional beast - a good read for those interested is Portia Di Rossi's Unbearable Lightness on how Hollywood applauded her eating disorder. Its not surprising that few children come through growing up there unscathed. But you can't look at Hollywood and think that is what life is like for all child performers, because it isn't.
