Perhaps if I had not watched von Sternberg's SCARLET EMPRESS the day before I watched IVAN THE TERRIBLE, I would have appreciated Eisenstein's film more.
SCARLET EMPRESS is von Sternberg's own historical Russian epic: Catherine the Great (played by Marlene Deitrich) rises to power despite conspiracies against her--conspiracies much like the ones that face Ivan in Eisenstein's film. The films are remarkably similar, and Eisenstein's influence on von Sternberg's lighting and montage sequences could not be more apparent.
Unfortunately, IVAN THE TERRIBLE is light years behind SCARLET EMPRESS in terms of the integration of sound with image, humanistic characterizations, and nuanced (as opposed to exaggeratedly theatrical) acting styles. If I had to guess, I'd say IVAN THE TERRIBLE was made ten years before SCARLET EMPRESS. In fact, it was made ten years after.
I'm a big fan of Eisenstein's BATTLESHIP POTEMPKIN, and as a student of Russian history and culture, I expected IVAN THE TERRIBLE to be a thoroughly engaging film. Instead it seemed a primitive effort: a move backward for a man who excelled at silent storytelling but couldn't evolve along with cinema. Of course, this IS Eisenstein, and IVAN is a very intelligent and well-crafted film, but viewed alongside its contemporaries, its shortcomings become all too apparent.
