It was one of the most attended films in the Soviet Union in 1973, with more than 60 million tickets sold. Plot The story begins in 1973 Moscow, where engineer Aleksandr "Shurik" Timofeyev (Aleksandr Demyanenko) is working on a time machine in his apartment. By accident, he sends Ivan Vasilievich Bunsha (Yury Yakovlev), superintendent of his apartment building, and George Miloslavsky (Leonid Kuravlyov), a burglar, back into the time of Ivan IV "The Terrible". The pair is forced to disguise themselves, with Bunsha dressing up as Ivan IV (tsar) and Miloslavsky as a knyaz (duke) of the same name. At the same time, the real Ivan IV (also played by Yury Yakovlev) is sent by the same machine into Shurik's apartment, he has to deal with modern-day life while Shurik tries to fix the machine so that everyone can be brought back to their proper place in time. Superintendent Bunsha and Tsar Ivan IV the Terrible are lookalikes but have completely different personalities, which results in funny situations of mistaken identity. As the police (tipped off by a neighbor who was burgled by Miloslavsky) close in on Shurik, who is frantically trying to repair the machine, the cover of Bunsha and Miloslavsky is blown and they have to fight off the Streltsy, who have figured out that Bunsha is an impostor. The movie ends with Bunsha, Miloslavsky, and Ivan IV all transported back to their proper places, although the entire episode is revealed to be a dream by Shurik... or was it?
