For those of you who "collect" cave-related films, I watched one a few weeks ago that I would like to make you aware of.
It's a Spanish film, "Night of the Sunflowers", or "La Noche de los Girasoles". It features a speleologist who comes to a village, which is slowly dying as its inhabitants move to the city, to investigate a cave that a local has found. The village mayor hopes it will have cave paintings, and revitalise the village with the tourist trade that will develop.
But things turn out differently.
It's good to see cavers being used simply as part of the plot, with no hype, no over-dramatisation, and properly filmed underground shots.
