Been doing some watching of Ostrov again. I got the Film Movement copy from Netflix which has much better English subtitles. I did some more ‘net searching and found this interesting tidbit at Ostrov (film) – Wikipedia, the free encyclopedia:
Pyotr Mamonov, who plays the lead character, formerly one of the few rock musicians in USSR, converted to Eastern Orthodoxy in the 1990s and lives now in an isolated village. Pavel Lungin said about him that “to a large extent, he played himself.” Mamonov received a blessing from his confessor for playing the character.
I would love to meet Mr. Mamanov. His portrayal of the fictional Fr. Anatoli has been powerful for me, creating some fruitful reflection.
