That IMDB page http://www.imdb.com/title/tt2820852/ has several videos on it. It's possible that one of them was infringing. But even if it was, I doubt they would really want to delist the whole page from Google searches.
Just as a likely scenario that there could be a comment with a download link in it, download links are very commonly shared on twitter and Reddit so who knows...
The tech dirt article about hacking team is also a gem.
