A railway bridge over the Neretva in Jablanica was destroyed. Director Bulajić's justification for demolishing the bridge rather than getting the shots in studio was that it would become a tourist attraction. The bridge was thus blown but because none of the footage was usable due to the billowing smoke that made it impossible to see anything, it was decided that the bridge should be repaired and destroyed again. The problem with the excessive smoke occurred again and the scenes of the bridge being blown up in the film were shot using a table-size replica at a sound stage in Prague. The Yugoslav public was updated on the shooting progress via pieces in the country's print media.
