Midnight screenings of Harry Potter and the Half-Blood Prince could have pulled in as much as $20 million, Variety is reporting, which would beat previous record-holder The Dark Knight by $2 million. The narrative over the coming days will be to see if it will break the all-time opening weekend record of $155 million, also held by Dark Knight. All of this only lends credence to our voiced suspicions that Potter is this year's broody, becowled vigilante, which could prove propitious come Oscar time. THR now has it at $22.2 million. [Variety]
