Alan Rickman (about the young actors growing up during the series): You know that they’ve got a little bit taller since a year ago, their voices change a bit, but it isn’t really until you get the shock horror of seeing a clip from the first film that you realise how vulnerable and small these people were, now I’m looking at a situation where, certainly with Emma off at University and Dan dancing his way through a Broadway show 8 times a week, it’s like the world has shifted.
