No Harry Potter expert, I, but Dylan Callaghan has a nice, short and very to-the-point interview with the writer of the fifth film, Michael Goldenberg, on the Writers Guild of America site. Regardless what one thinks of the movie — and the book is said to be somewhat unwieldy in its adaptability, perhaps a smartly chosen break for scripter Steve Kloves — I think Goldenberg’s comments about organic restrictions is a smart one, and one that obviously informs The Order of the Phoenix.
