Today is the anniversary of the death in 1948 of Soviet film director Sergei Eisenstein. He directed Strike (1925), Battleship Potemkin (1925), October or Ten Days That Shook the World (1928) and Alexander Nevsky (1938).
I have not yet seen Ivan the Terrible, parts 1 (1944) and 2 (1946/1958), which can be seen here:
Criterion Contraption has a review.
There is more information on Eisenstein at Senses of Cinema, the World Socialist Web Site and FilmReference.com. A Film Canon has a review and a review of part 2 here.
