Kick-Ass was the second most downloaded movie of 2010, according to TorrentFreak, trailing only Avatar.  The blog tallied 11.4 million illegal Kick-Ass downloads using its methodology, which combines info from thousands of BitTorrent trackers.  The number of Kick-Ass downloads would have been made it #1 in 2010, when Star Trek was #1 with just under 11 million downloads. 

 

Kick-Ass was something of a cult hit despite its modest box office take, driving sales of the graphic novel on which it was based to #1 in both comic (see “Top 300 Graphic Novels—April 2010”) and book stores (see “Kick-Ass Is #1”). 

 

Avatar was the #1 downloaded movie of 2010, at 16.6 million (and a box office take roughly 25 times that of Kick-Ass).  Inception was #3, Shutter Island #4, and Iron Man 2 #5.
