The shots over Wroclaw were filmed from the top of a church near the main square. it took three visits to gain entry, the first time it was closed.
The second time it must of recently closed although no one had checked if there were still any visitors in the tower. I could hear people banging and shouting from behind a strong wooden door. I was wondering where to go and get help when someone arrived with a bunch of keys and let the prisoners out!
Third time I was lucky!
