Los Angeles: A swan song of the blockbuster Harry Potter series eclipsed a previous trailblazer of the Hollywood tent poles by grabbing a heart-stopping USD 168.55 million over the weekend, as well as creating three other firsts as the highly popular franchise bows out of celluloid incarnation for good, media reported.

According to estimated statistics released by Warner Bros., which distributes 'Harry Potter and the Deathly Hallows: Part II', the final and eighth installment on the boy wizard franchise opened as No. 1 in North America box office Friday, grossing USD 91.2 million from 4,375 venues in the US and Canada.

It broke the milestone for all-time highest single-day gross which was held by 'The Twilight Saga: New Moon', which garnered USD 72.7 million when it opened Friday, November 20, 2009.

On Saturday, it continued with the foray at box office derby, finishing the business with USD 42.85 million. All told, the finale of the series has also managed to become No. 1 in three other areas: largest midnight gross (USD 43.5 million), largest opening weekend -- 'Harry Potter and the Deathly Hallows -- Part 1', hit the screens last November, previously held that record with USD 125 million in ticket sales upon its debut, and largest IMAX opening (USD 15.5 million from 274 theaters).

'Transformers: Dark of the Moon,' Paramount Pictures' third 'Transformer' installment, continued its money-making business, and is estimated to take in USD 21.25 million, finishing as No. 2 at the box office. It has garnered a cumulative sales totalling USD 302.8 million over three weeks.
