[on shooting
Dukla 61 (2018) in real coal mines]: "The filming took place first around Rakovnik. The underground space fascinated me. It was one big adventure in which we didn't enjoy much light, because we spent a lot of time under the surface, at a depth of 100 meters. Even so, it was a completely different world. It wasn't hot, we didn't enjoy it until we were eleven hundred meters underground in Ostrava. There we were already pouring because it was so hot, thirty degrees Celsius. In Rakovník it was only eleven degrees, so it was quite cold. That's why we were always made up to look like we were pouring, and we were lubricated with special oil. We pretended to be sweaty while gnashed our teeth a bit."
