WorstPreviews.com has posted the first sneak peaks at the production of Harry Potter and the Half-Blood Prince, the second to last film/book in the Potter series. Don’t let the “worst previews” name fool you - these two videos, while giving a fairly minimal look at the movie itself, show interesting bits of film production such as an evolution in the Potter costumes and the set design of Wool’s Orphanage. The Half-Blood Prince is slated to open a year from now, on November 21, 2008, and will see the return of all of the film’s principal actors. Click the link below to see the production videos.
