The fifth Harry Potter movie is still months away, but according to Newsweek, the sixth movie Harry Potter and the Half-Blood Prince is already being worked on.

The news comes from an interview with Stuart Craig, who has served as art director on all five of the previous Potter movies. Craig tells them that the sixth film “has to be impressive and beautiful and poignant. So I'm looking forward to doing that.”

Though they are already underway creating the look of the movie, it’s likely to be some time before any of the cast shows up to start filming. They’ll start doing press to promote the fifth film soon, and that should keep all of them pretty occupied through the summer.

Right now the sixth movie is scheduled for a November 21st, 2008 release date, so there’s no rush. The fifth film, Harry Potter and the Order of the Phoenix arrives July 13th of this year.
