Last month, rumors began to surface that Warner Bros. was going to release ultimate editions of the first two “Harry Potter” movies. While no one was sure if it would be theatrical or on home video, today WB officially announced the titles and they are home video releases.

So to help promote the December 8^th release, WB has cut a new trailer which details what you can expect to see on the DVD’s and Blu-rays and if you’re a fan of the “Harry Potter” franchise, I’m sorry to say…you’ll be double dipping this holiday season. Watch the trailer and read about the extras after the jump:

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.

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.
