I'm accepting this addition to the site for now, but I have been unable to find any confirmation that the Latvian "Auseklis" studio ever existed (it's not mentioned in the film), nor any record of this film, nor the year in which it was made (the film itself does not mention it), nor anything about the two people listed at the beginning as the creators - U. Lapins & M. Treimanis. The video comes from the YouTube channel of the person who added it to this site (Gennady Zakharov), and he lists "Улдинс Лапиньш" (Uldins Lapins) as being the director, but I've been unable to find anything about this person online under any spelling. Also, I'm not even sure that "Uldins" is a real name, as I only find results for "Uldis".

So I can't vouch for the accuracy of the information about this film.

Also, the film is untranslated (has no subtitles), so it doesn't appear on the main page for now. The voices repeat "21" until about 00:49, then say something else, but I don't know what.

Admin, I found this information on mults.info

Thank you, after typing "Лапиньш site:mults.info" into Google I found this forum thread with some info about his films (also, I was right that the name is "Uldis", not "Uldins"), and later found this Latvian-language biography and this English-language academic article. I've added the info to his bio. In the future, please don't hesitate to mention your sources when adding info (especially if it is obscure). :)
