According to some sources, this was the last film being shot in Berlin Babelsberg, when the Soviet tanks Rolled in the UFA studios in April 1945. Outside Berlin, work was still going on with "Das Leben Geht Weiter", and in Prag the filming continued with "Fledermaus" and "Shiva und die Galgenblume" until the very last days of the war. "Sag die Wahrheit" was later completed with some replacements in the cast.
