I must admit that I participated in getting this movie on number 1 on this chart.... BUT, I also saw this movie in the opening weekend in the theater, and I own the movie on a Blu-Ray disc.
Since I don't have the capabilities to rip the movie myself, I downloaded the ripped version. No nag screens and other crap on the downloaded version, so I prefer to watch the ripped/downloaded version over the original Blu-Ray disc (also see this posting) on my Popcorn Hour media player.
So being the most downloaded movie doesn't necessarily mean most pirated (in my opinion).
Sure, there still are lots of people who'll pirate anything they get their hands on, but that doesn't mean that they would even think about going to the cinema or buy the disc. The studios wouldn't make money of them anyway.
But hé, that's just my humble opinion........
