The film is an adaptation of Marie Pujmanová's novel Premonition. Originally Miroslav Cikán tried to make the film in 1944 with Jana Dítětová in the main role, but the production was canceled only after a few days of filming.[1] Otakar Vávra re-wrote the screenplay and made his 1947 version with a different cast. František Smolík played the role of the father in both films.[1][2]
