Hej,

at eo.lernu.net-forum the movie Već Viđeno (1987) mentioned. The Youtube video has English subtitles. Click the CC-button. At 0:04:15 continuing Esperanto is mentioned. I didn't finish to watch the whole movie yet. So I don't know what it is all about. Firstly only the "đ" letter found my attention, which is an typical Serbian letter. Serbian seems to sound something similar to Russian, which I had to learn at school.

Ah, yes, that's interesting. The movie is also mentioned ĉe filmoj.net: Vec vidjeno / Jugoslavio, 1987. Rolulo estas instruisto de Esperanto.

ĝp,
