Schweitzer, in the process of reworking Leonov's script so that it would be more suited for the present time, decided to express the author's idea through songs. Since the film was made in the American style, the idea arose to use the method of end-to-end ballads widely used in American films. The option of inviting
Dean Reed was considered, however, Schweitzer's wife came up with the idea of hiring
Vladimir Vysotsky. Vysotsky wrote the ballads, but his music was mostly unsuitable for the picture. Composer of the film's score Schwartz refused to write his own music to tyje ballads which was why some music was written by Anatoly Kalvarsky. Most ballads were truncated to fit the film and some of them were removed when already long film was shortened. Outdoor scenes of the film were mostly shot in
Budapest. ==Reception==
