Warner Bros. Pictures has moved "Harry Potter and the Half-Blood Prince" up two day.
Instead of Friday July 17th, the film will bow on Wednesday July 15th. The move emulates "Harry Potter and the Order of the Phoenix" which did a similar move and earned $44 million on the Wednesday. In total it brought in $139 million over the five-day period.
A new trailer for the film goes online at 9pm US-EDT this Thursday.
