As one of the producers of the “Harry Potter” films, David Heyman has done the impossible - he made the beloved books work brilliantly as standalone movies. And the most recent - “Harry Potter and the Half-Blood Prince” - is getting some of the best reviews yet. In fact, many have called it the best of the series.

Anyway, while “Half-Blood Prince” has just been released, David and the “Potter” team have been hard at work for the past three months on the final film, which is being released as a two-parter in November 2010 and July 2011. Since he was cool to talk about everything, we spent almost thirty minutes discussing all three films.

After the jump you can read about changes from the book to the screen, deleted scenes, the running time for “Deathly Hallows”, will there be a trailer for part two on part one, how long will the final battle be in part two, what else he’s producing, and a lot more! It’s a great interview and a must-read if you’re a “Harry Potter” fan.
