LONDON - The latest instalment in the Harry Potter film could help make the franchise as one of the most successful franchises of all time, owing to the huge merchandising that comes with it.

The first five Harry Potter movies have been a massive source of revenue and profit for Warner Bros.

The franchise has earned a whopping 4.5 billion dollars, an average of 897 million dollars, at the box office alone, making it the most successful film franchise of all time, behind James Bond

And it is believed that the release of the new film, ‘Harry Potter and the Half-Blood Prince’, could push the Bond franchise back into second place.

In addition, it has earned 2.7 billion dollars from DVD sales, which makes for 211 million units, reports the Telegraph.

Video games have sold 1 billion dollars, more than 40 million units, while Warner Bros also makes hundreds of millions of dollars from merchandise and other sales such as downloads on iTunes.

After the DVD released of the ‘Half-Blood Prince’ later this year, a Lego video game based on Harry, Ron and Hermione’s first four years at Hogwarts, is due in 2010.

A theme park ‘The Wizarding World of Harry Potter’ is due to open in Orlando, Florida in spring 2010.

There is also the inevitable toy and clothing ranges which produce products such as interactive wands, Harry Potter-style glasses, Gryffindor scarves and a raft of action figures.

Mattel are set to release a new version of their popular ‘Scene It?’ interactive boardgames.

Harry Potter lovers can also expect top trumps, sticker albums and costumes. (ANI)
