A high resolution version of District 9 was downloaded over 1 million times within 24 hours of appearing online

"With over a million downloads in less than 24 hours, Peter Jackson’s Sci-Fi thriller District 9 is well on its way to becoming the most pirated movie of 2009. The huge download spike is caused by a DVD quality version of the movie that leaked onto various BitTorrent sites yesterday.
In the present day and age, no blockbuster movie can escape the fate of being pirated. However, the popularity of the various rips and titles can differ drastically, and a recent leak of a high quality version of Sci-Fi thriller District 9 might become a record breaker.
Two weeks ago a Telesync version of District 9 already found its way onto the Internet, but the rate at which the freshly released R5 release is being downloaded easily beats all other titles released in 2009 to date.
At the time of writing the movie has been downloaded over a million times on BitTorrent alone, less than 24 hours after it first surfaced. There are a few dozen torrents out there already, and the most popular one has over 50,000 people downloading the movie simultaneously."
