Described by many fans as the end of an era, the final film in the Harry Potter franchise - The Deathly Hallows Part 2 - premièred in London yesterday.

After days of waiting, thousands of fans finally got the opportunity to see the stars of the film, Emma Watson, Rupert Grint and Daniel Radcliffe walk the red carpet together for one last time.

Author of the seven part series, JK Rowling, was also in attendance at the event which took over Trafalgar Square and screened at Leicester Square. The final film is due to be released next Friday, 15th July.

But how do the books and films compare? Any fan will tell you the books get larger and the films get longer but how do they compare in the sales charts and box offices of the UK?

Harry Potter and the Philosopher's Stone, released in 2001, still holds the record - out of all the Harry Potter films - for the highest grossing film at the UK box office at £66.1m. All eyes are on the final instalment to see if it will beat all previous films.

The previous film, Deathly Hallows part 1, topped UK box offices with total sales of £18.3m during the opening weekend.

We have gathered data from Nielsen Bookscan, the world's largest book tracking service, as they collect total transaction data directly from the tills and dispatch systems of all major book retailers and have published the full list previously to show the top 100 bestselling books of all time.

The book series as written by JK Rowling also shows that the Philosopher's Stone, although the shortest at 223 pages, is the most popular with a volume of 3,844,316 sales during 2008-2010.

The highest sales value was brought in by Harry Potter and the Order of the Phoenix, which grossed £33.9m in the UK during 1998 - week ending 11th December 2010. Harry Potter and the Half-Blood Prince follows in second place with sales of over £25m. Interestingly the millions of readers who have read all the books from start to finish will have read 3,407 pages of wizard fiction in total.

We have gathered the data for the volume and sales of all the books via Nielsen Bookscan and thanks to the UK Film Council we also have the box office sales for all the films. What can you do with this data?
