If you are looking to target countries for a torrent download site, I'd have to say it would be US top of the list and UK next. However, you'll need to take into consideration how many countries can't afford to pay for going to the movies or even buying a movie in the store to watch at home. Even in some countries, movie rentals are quite high. People can't afford to invest in buying or joining a streaming site to watch films. So they resort to downloading torrent films to watch at home. In a torrent site for movies, it is best to have movies with different languages and or subtitles so you can attract more visitors to your site. In most cases, torrent sites target everyone, because there are so many people who are interested in downloading movies for free.
