Each year TorrentFreak compiles a list of the top ten most pirated films and television series of the year, and they recently released their new lists for 2013. I wouldn't say there are a ton of surprises on either list, but it's still interesting to see what people pirated the most last year.

Of course most of the highest grossing films of the year also ended up being the most pirated of 2013, however blockbusters like MAN OF STEEL and THE HUNGER GAMES didn't make the list. The biggest surprise on the movie list though might be GANGSTER SQUAD, which didn't do well in theaters or with critics. On the television side of things, this is the second year in a row HBO's Game of Thrones has been at the top of the list of most pirated TV shows.
