Harry Potter and the Half-Blood Prince grossed an eye-popping $22.2 million from its midnight showings early Wednesday morning, according to figures released by That breaks the $18.5 million midnight record previously held by last year’s smash The Dark Knight, and it’s well ahead of the $16 million Transformers: Revenge of the Fallen grossed in its midnight showings earlier this summer. If these magical numbers hold up, Half-Blood could have a shot at topping The Dark Knight‘s $203.8 million five-day opening-weekend record as well.
