An extra examining the use of fairy tales in Eastern European film would be very interesting.
Your wish is my command (oh the irony) - that's precisely what I'm working on right now!
Although I'm sticking to Czech film and very occasional mentions of Soviet titles rather than eastern European film in general, as there wasn't much of a fairytale tradition in other eastern European cinemas, at least as far as I can make out. Certainly not one as indelibly embedded in the culture as it was in Czechoslovakia, where half the top ten box office hits for the whole of the 1950s were fairytales, including the first four, and the top two may be the biggest homegrown Czech blockbusters ever - now that our viewing is much more fragmented, it's hard to imagine anything else selling eight million tickets domestically, as Bořivoj Zeman's The Proud Princess
did in 1952. Two decades later, Three Wishes for Cinderella
was the biggest blockbuster of 1973 by almost a 100% margin.
Romanian cinema certainly had a fair few fairy tale films, most notably the films of Elisabeta Bostan. Her more famous films are still shown every Easter in Romania and still much loved.
Her early films share many similarities with the Soviet era films, though of course this is not a huge surprise given Romania's cultural proximity to the USSR at the time.
There is a box-set containing Seven of her films available, but it seems there are no English subtitles. I have this set so I should really check if they have subs, as I have come across a few Romanian DVD that actually have subtitles not listed on the boxes. On original release, some of these films were dubbed into English by international distributors, and some of these versions still exist in rips from VHS sources.
These films are beautiful to look at, not always the case with communist Romanian films, I've had no problem sitting through some of these films on TV at Easter with a very poor understanding of Romanian.
