Johnny Depp could be making an appearance at the long-awaited opening of the Roald Dahl Museum and Story Centre in Buckinghamshire on June 10. It's hoped that the star of Charlie and the Chocolate Factory (which opens in July) will be joined by authors JK Rowling, Philip Pullman and Jacqueline Wilson, all of whom have contributed to the centre's all-important creative writing section. This will reveal all manner of juicy tidbits to aspiring young writers, such as the fact that it took Dahl seven attempts at James and the Giant Peach before he got it right - and that it was originally a cherry.
