They don't name the films but I found this quote on the BBC site
"Their site piracydata.org has been collating the weekly top 10 most-pirated films and investigating whether legal digital methods were available.
They found that half of the movies in the list were not available to access legally online. Furthermore, none of the 10 titles could be streamed - arguably the most straightforward way to consume media online." http://www.bbc.co.uk/news/technology-24580130
