Many years ago I saw a film on television but I couldn't remember what it was called. I knew it was an European film, that it was set in the Middle Ages, that it was about a boy searching the countryside on a quest and that there was the constant threat of plague. (It's not The Navigator, a Medieval Odyssey which is better known - that was an Australian/New Zealand film, not European).
I had tried to find it some years ago without success but I think I've found it. You may have heard of The Singing Ringing Tree (1957). It's reputed to be quite a scary film considering that it's a childrens film. I haven't seen it though one can get it on DVD but apparently there's a strobing effect on the DVD which I waould find really offputting. The film was made by an East Germany (as it was at the time) film company called DEFA. They made other childrens films based on the likes of the stories of the Brothers Grimm. Closer to the dark stories of Grimm rather than the Disneyfied versions.
I think the film is "Dar Licht der Liebe" which means The Light of Love (1991). I found a DVD on the German site of Amazon and using Google Translate, the description sounds right. It was made by DEFA and the date of the film makes sense.
I've ordered a copy and will see if I'm right. (same DVD region as UK and it mentions that there are English titles).
