I was at an Alamo Drafthouse this weekend, and they usually have a fun pre-show with all kinds of strange bits and clips and such. This weekend they had one that really caught my attention, a short film punctuated with commercials and movie trailers, so I missed bits and pieces. Plus they were taking my order at the time.
It was a stop-motion animation fantasy sequence. Some form of love story between a female being made of light, and a male monster that looked something like a satyr. They were in an underground cave and surrounded by garbling monsters, and apparently there was a green twig which would make the monsters blink out of existence. A human man sat and watched the whole thing.
In the end, the night ended, and we see a man and a woman seemingly sleepwalk away from the cave and return to town to climb back into their homes. We follow the man and see it was the man warning the whole story. He wakes up, turns, and picks up a note which I think was translated as a happy birthday note, then the movie ended.
The parts I saw were speechless, playing music and foley effects. I believe it had Cyrillic characters, so I would guess Russian. The end of the credits said 1987 but I couldn't read anything else.
I asked the name of what I was watching and was told "oh, it's just our pre-show. We find and play all kinds of clips of things from YouTube" which didn't help at all. I would like to watch it from start to finish.
