Cave of the Yellow Dog (U)

Its stars are a genuine nomadic family who live on the Mongolian plains, and, while the writer-director gave them some scenes to act out, they only ever act as themselves. Much of the film comprises footage of the children playing, sometimes not even realising they're on camera.

There's a wisp of a story about a six-year-old bringing a stray dog home from the mountains, but what's really captivating is seeing how a yurt is dismantled and packed onto a caravan of yak-drawn carts, and how a pancake of dried dung can be used as a child's toy. "Mum, can I have some dung?" isn't a subtitle you read very often.
