Part of chapter 2 of my book covers some copyright disputes over children's literature and I often look out for any news of these kinds of cases. The latest in a long line of cases has just been heard in the US in a dispute over the rights to the Chitty Chitty Bang Bang film. The judge has said the issues are substantive and told the two sides to prepare for trial. It will be an interesting one to watch.
Incidentally if you do have children I highly recommend Ian Flemming's original book, which is significantly different to the film.
Update: By coincidence the trustees of the Great Ormond Street Hospital have just launched the official sequel to Peter Pan, Peter Pan in Scarlet by Geraldine McCaughrean. The Peter Pan copyright disputes, such as that surrounding Emily Somma's unauthorised sequel, After the Rain, have been amongst the most interesting.
