The films of Andrei Tarkovsky, the man Ingmar Bergman described as the greatest director, "the one who invented a new language, true to the nature of film, as it captures life as a reflection, life as a dream," may find new and wider audiences now.
FilmAnnex.com has digitized all of his feature films, and is offering them up for watching and embedding all over the Internet. The Russian Film and Culture Archive also has some great interviews with and about Tarkovsky. In fact, that embed up there is his film Nostalghia, which is largely in Italian with English subtitles. From my casual browsing, the quality of the prints and digitization is good, if not exactly HD.
It used to be that to get films like this you had to go to some highbrow and out of the way video store, where the clerks all thought they were the next Quentin Tarantino, but with better hair and funnier.
