The boy who lived on DVD and Blu-ray will now be getting an Ultra HD makeover just in time for Christmas. The complete Harry Potter film collection is coming to 4K Blu-ray on November 27.

So that's all eight main-line movies, (Harry Potter and the Sorcerer’s Stone, Chamber of Secrets, Prisoner of Azkaban, Goblet of Fire, Order of the Phoenix, Half-Blood Prince, and the Deathly Hallows – Part 1 and Part 2), freshly remastered to take advantage of the fancy new-ish format, complete with DTS:X audio.
