Harry Potter and the Half-Blood Prince, the latest Harry Potter series, has stormed the box office like never before, witnessing a wonderful opening. It has broken the old record for Wednesday midnight screenings of $18.5 million held by the Batman movie The Dark Knight, which was released last year.

The Dark Knight holds the highest one-day US box office record by $67.1 million and went on to $203.7 million in its first five days in theatres. It's overall earning worldwide was $1 billion. The five Harry Potter films based on the books written by J.K. Rowling have raked in $4.5 billion worldwide.

There was scepticism around the recently released Harry Potter and the Half-Blood Prince due to the ongoing economic recession and the entrance of other franchises like the Twilight films. Many thought that Twilight films would steal away Harry Potter audience. But reality proved otherwise, with tickets of Harry Potter and the Half-Blood Prince selling like hot cakes. Maybe the two-years gap between the last Harry Potter film and the latest offering has created curiosity amongst the film lovers.

Now, talks are doing the rounds that Harry Potter film series would topple even James Bond movies as the top earning franchise in box office history. James Bond movies earned 5 billion dollars from 22 films while five Harry Potter films have already raked in 4.48 dollars billion. With the release of Harry Potter and the Half-Blood Prince and more films in the offing, it has every chance to beat James Bond movies.

More than the performance of the film at the box office, its lead actors Daniel Radcliffe, Emma Watson and Rupert Grint have become a rage amongst the film buffs especial teenagers.
