still now, a fairly prestigious location of Moscow, which is not too far from the Kremlin. Rostov Kremlin, Rostov, USSR Yalta, USSR Props The time machine for the film was created by the artist, wood sculptor and cartoonist Vyacheslav Pochechuev. The original version of the time machine, manufactured by a special bureau, turned out to be an expressionless layout of a standard computer. Pochechuev sketched a new model and, with the help of a designer, a locksmith and a glassblower, created a new time machine in a few days, causing the audience to feel a miracle . Pochechuev received a prize of 40 rubles, and in the certificate from the accounting department it was written: "The money was issued for the invention of a time machine." Soundtrack Nina Brodskaya performed the song "Zvenit yanvarskaya vyuga" () for the film. It was also recorded by Sofia Rotaru. In 2014, Italian pop punk band Vanilla Sky recorded a cover of this song along with music video. Lev Polosin & Boris Kuznetsov and the Moscow Military District Choir performed the song "Cap-cap-cap" ("Marusya"). Valery Zolotukhin performed the song «Razgovor so schast'em» (). Deviations from the original play The original play was written by Bulgakov in 1935 (albeit not published until 1965) and, therefore, used a setting typical to the 1930s. The film, released in 1973, made changes to the setting to make it contemporary. For instance, Shpak's phonograph was replaced in the film with a tape recorder, and the time machine was envisioned as using more advanced technology such as transistors. In addition, inventor Timofeyev is inspired to travel to Ivan IV's era after Miloslavsky recitaring the book about Ivan IV, as opposed to listening to the opera The Maid of Pskov on the radio. There were other deviations, not related to changes designed to modernize the setting. While the inventor's surname Timofeyev was retained, he was called Nikolai (nicknamed "Koka" by his wife Zinaida), while in the film, his name is Alexander (called "Shurik" informally). He is presumably an older version of the protagonist of two previous Leonid Gaidai films: Operation Y and Other Shurik's Adventures and Kidnapping, Caucasian Style, played by the same actor, Aleksandr Demyanenko; this connection, though, is not stated outright and neither of these earlier films are referenced. In addition, the reason for the time machine malfunction was changed. In the original play, Bunsha and Miloslavsky knowingly disable
