Zabranjeno Pušenje's first album was entitled Das ist Walter as an homage to this film.

When a German asks to a guy from Sarajevo “but who is Valter ?”, the other guy answers him : “Das Ist Walter !”, showing the whole town.

Thanks to its communist resistance theme, this film was a great popular success in Yugoslavia, but also in China ! Thus, during the NATO bombing of Belgrade, the USA stroke the ambassy of China. The actor who was playing Valter, Bata Zivoinović, went to meet the wounded Chinese in the hospital : they greatly appreciated !
