While I think the "Harry Potter" films have undoubtedly improved since they first arrived back in 2001, my favorite thus far, "Harry Potter and the Order of the Phoenix" was scripted by Michael Goldenberg, not Steve Kloves who has written all the other Potter films.  Kloves returns to the series with "Harry Potter and the Half-Blood Prince" and speaking wit the LA Times, he had some interesting things to say about what to expect in the new film and his personal history with the series.

On why he didn't write "Order of the Phoenix":

This will sound glib, but it's somewhat true: They asked me on the wrong day. They asked me for the last time on the wrong day. Had they asked me the next day, I probably would have said yes. There's always stuff that goes on around these movies and I felt an urge -- and I still feel an urge -- to do other things. To go back to making movies nobody wants to see, and I'll do so. But I think I was feeling that urge particularly keenly at that time.

"Harry Potter and the Half-Blood Prince" hits theatres on July 15th.

On the climactic scene between Dumbledore and Snape:

It is informed by everything [Potter readers] have come to know is true. So if you watch the film carefully, there are performance moments that are quite extraordinary, Alan Rickman [who plays Snape] especially. There is something we added that you can look forward to, a short scene between Harry and Snape prior to the big event. It'll be interesting to see how it plays to the audience. It should be a haunting moment for Harry. While I was writing, I just had a notion about a moment between him and Snape, something Harry could look back on and question as to why he didn't act differently.

On working with J.K. Rowling:

A range of things, even something really simple. I once asked about the 12 uses of dragon's blood, which is referenced in the books. There are writers who would write "12 uses of dragon's blood" and not have a clue what they are; it just sounds cool. But I emailed her to ask (and this was 10 years ago), and 25 seconds later I get an email back with a list.
