Considering that even Eisenstein studied D.W. Grifffith, I'd say it's safe to
say Hollywood has influenced Russian production. My anecdotal observation
(after spending 6 months in Russia and seeing a lot of ordinary, theatrical
fare as well as Russian classics unavailable in this country) is that most
narrative films from Stalin forward tend to be similar to Classical Hollywood
narratives in David Bordwell's sense of the word. Soviet socialist realism,
like Hollywood, requires its film products to be accessible. Whether socialist
or capitalist, the circumstances of production and the pressure to reach a wide
audience create certain ideological restraints. Instead of 'boy meets girl,'
they're more like 'boy meets tractor.' All this having changed a lot since
glasnost, of course. And the exceptions to the rule, like Tarkovsky. There's
a whole spate of new books out on Russian/Soviet cinema--unfortunately I can't
give you the exact titles because I loaned them all to a student (from Moscow)
writing a paper about Tarkovsky.
hope this helps a bit,
