It was a record-breaking week on Blu-ray as Harry Potter and the Deathly Hallows, Part 2 made its debut on the home market. That film crushed competition selling 2.71 million units / $60.75 million during its debut, which is even more impressive, as it was released on Friday and not Tuesday. By comparison, Avatar sold 2.55 million units and generated $52.80 million during its debut. (It was also a Friday release, so the comparisons are valid.)
Its opening Blu-ray ratio was 49%, which is a little lower than some first run releases have earned. However, I think some of the people who are most likely to buy the films on high definition would either grab the Box Set, or perhaps are waiting for next year's Uber collection.
Even without taking into account the box set numbers, the film is instantly in seventh place on the all time chart and, by this time next week, it should be in second place.
Warner must be happy.
