Not long ago, I've watched a film called "Dancer in the dark". It is a really sad story about a poor woman with a rampant / chronic disease, damaging her eyesight. The disease has also affected her son. The famous Icelandic actress and talented singer, Björk Gudmundsdóttir, played the main character and performed the songs. It's a sad movie, but I really enjoyed it and would highly recommend it.
