H ow can we forget the woman who started it all? Author J K Rowling of the hugely successful boy wizard books also put in an appearance.

We wonder how she feels about several new scenes in the film that did not appear in the book.

'We've added a couple of sequences which aren't in the book that I think raise the emotional stakes and the jeopardy stakes,' the Daily Mail quoted Director David Yates as saying.

The scene takes place in a tent.

'We've added a scene where [Harry] finds Hermione listening to some Muggle music and they have a dance with each other, which is a very tender, awkward and emotional moment for the two of them.

'There is always that question -- they have a very special friendship as characters and there is always that moment where you think, could this trip beyond friendship to something else?

'In the book, JK alludes to that but she doesn't actually show it. I wanted to show it on film because I thought it would be a very interesting thing.
