J K Rowling on writing book five of the series. As the kid who plays Harry in the films looks so much like a miniature Harry Enfield, you can imagine this as his ‘Kevin the Teenager’ book.

Harry, who is now 15, has some excruciatingly embarrassing scenes in the new book. �He is very much in puberty,� [Rowling] says. �I just think it is a very confusing time. Yes, he�s very confused in a boy way. He doesn�t understand how girls� minds work.�
