On The Mad Monk's Wall

Naryna Jesse, You wrote in your post in the theme FAVORITE SILENT FILMS/DIRECTORS that you were trying to remember Ukrainian director "ostensibly making silent films.... black-and-white films, one is about swans." It can be the late responce, but... I'm from Ukraine and I have only one suggestion that it could be Felix Sobolev who actually did documentaries, and he filmed such movies as Language of Animals, 1967, Can Animals Think, 1970 etc.
