The final bombing scene was originally meant to include wild animals from the bombed Belgrade Zoo roaming through the city's downtown, which indeed happened during actual 6 April 1941 Luftwaffe air-raids; in fact, an old newspaper article documenting this bizarre occurrence served as inspiration for the author Dušan Kovačević to include it in the film. However, at the time of movie's filming in 1980, Tito died, which resulted in the extended mourning period that effectively canceled all entertainment activities in the country - including the Italian circus tour that was meant to provide the animals for the scene. Since working with untrained zoo animals was deemed too dangerous, the film-makers reluctantly had to abandon the idea at the time. However, the idea was used in the opening scene of "Underground" (1995), some 15 years later.
