The film was shot at a specially built film complex "VoenFilm" in Medyn, where a village was built, pillboxes were dug, a river was built and filled with water, and part of the Varshavskoye Highway was dumped.[5] Historical consultants tried to achieve maximum reliability of what was shown, up to the reconstruction of the numbers of tanks and aircraft; in particular, Bezrukov's character is armed with a Thompson submachine gun, since such a weapon was found during excavations at the Ilyinsky border.
