That seems like a very odd film, but also oddly fascinating. How does one have standard pronunciation in a constructed language? The only association I have with Esperanto is this weird Swedish movie, 'Populärmusik från Vittula', where this kid ends up translating for a Ghanese priest to the congregation in a tiny country village because he'd learnt Esperanto off the radio (no one could speak the other languages he spoke after the original translator fainted). A rather absurd scene in a rather absurd movie.

Thank you for you Christmas card by the way! That was such a lovely surprise <3
