Reuters reports that J.J. Abrams’ “Star Trek” reboot was the most pirated film of 2009 with roughly 11 million illegal downloads.

Coming in a close second is “Transformers: Revenge of the Fallen” at 10.6 million downloads, according to data from TorrentFreak, a blog about filesharing.

While those two movies were among the biggest of the year at the box office, the third most-pirated film was a box office flop.

“RocknRolla,” the creation of Sherlock Holmes director Guy Ritchie, earned just $US 26 million ($29 million) worldwide.

Meanwhile, “X-Men Origins: Wolverine” which made headline news due to a workprint leak, came in at number 9 with 7.2 million downloads.

The list is rounded out by “The Hangover” at number 4, followed by “New Moon,” “District 9,” “Harry Potter and the Half-Blood Prince,” “State of Play” and “Knowing.”
