HBP's gross this weekend.

"With some of the best reviews of any "Harry Potter" movie, "Half-Blood Prince" was off to the fastest overall start in franchise history.The sixth movie about the young wizard came in $20 million ahead of the last movie, "Harry Potter and the Order of the Phoenix," which grossed $139.7 million domestically in its first five days two years ago. The new film had the second-highest start ever for a movie premiering on Wednesday, trailing the $200 million five-day opening for last month's "Transformers: Revenge of the Fallen."

"Half-Blood Prince" already has surpassed the $157.3 million "Order of the Phoenix" pulled in during its entire first week. By the end of its seventh day Tuesday, "Half-Blood Prince" will be in the $180 million range on its way to becoming the franchise's first $300 million domestic smash since the original movie, 2001's "Harry Potter and the Sorcerer's Stone," said Dan Fellman, Warner head of distribution."
