With 16,580,000 downloads on BitTorrent alone, Avatar is undisputedly the most pirated film of the year.

Never before have we seen this many downloads of a movie in a single year. This honor previously belonged to last year’s winner Star Trek with 10,960,000 downloads, but Avatar quashed this previous record.

Earlier this year we already crowned Avatar as the most downloaded Blu-ray film ever, with 200,000 downloads in just 4 days. In the months that followed the number of Blu-ray downloads of Avatar have exceeded two million.

Another expected entry in the list of most pirated movies in 2010 is The Hurt Locker. This film was already available on BitTorrent for most of 2009, but really started to gain attention from the public after it won six Oscars.

This huge success online compared to the meager box-office earnings was most likely one of the reasons why the makers of the film sued thousands of alleged BitTorrent users last spring. Despite the looming threat of legal action the downloads continued pretty much undeterred, resulting in a 9th place in todays list.

As every year there are also a few notable absentees, such as the two best grossing movies at the box-office this year, Toy Story 3 and Alice in Wonderland. On the other hand, Kick-Ass and Green Zone were both hugely popular among the downloading public, while their box office grosses were relatively modest.

The data for this list is collected by TorrentFreak from several sources, including reports from thousands of BitTorrent trackers. All release formats, including cammed versions are counted. Afterwards, the data is carefully checked and corrected.

The film’s success doesn’t stop at the box office either. Earlier this week the DVD was released, and on the first day in stores 3 million copies were sold in the United States, Canada and the UK.

Alongside these impressive real-world sales, the film beat the competition on BitTorrent and other filesharing networks too. With more than 7 million downloads on BitTorrent alone, The Dark Knight now holds the title of most pirated movie of 2008. Comments on various BitTorrent sites reveal that many downloaders obtained an illegal copy after they had already watched the movie in the movie theater.

As with every other blockbuster, ‘The Dark Knight’ was leaked onto the Internet in various formats. It began right after the premiere in July with a cammed version, which was celebrated by the folks from The Pirate Bay. The ‘cam’ was followed by a DVD-screener in early September, and a DVD in November. The latter release turned out to be the most popular among filesharers.

As we look over the rest of the top 10, we see that there are quite a few differences between popularity at the box office, and on filesharing networks. ‘Indiana Jones and the Kingdom of the Crystal Skull’, for example, came in second at the box office, but only came in 30th place in the download chart. On the contrary, ‘The Bank Job’ is the third most pirated movie on BitTorrent, but just 66th at the box office.

The data for this list is collected by TorrentFreak from several sources, including reports from all the large BitTorrent trackers. All formats, including cammed versions are counted, and based on previous experience a correction is made for smaller .torrent releases that we might have missed.
