Ivan Vasilievich Changes Profession Russian , Ivan Vasilyevich menyayet professiyu is a Soviet comic science fiction film directed by Leonid Gaidai in 1973. In the United States the film has sometimes been sold under the title Ivan Vasilievich Back to the Future. This film is based on the play Ivan Vasilievichru by Mikhail Bulgakov and was one of the most attended movies in the Soviet Union in 1973 with more than 60 million tickets sold.
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, Shpaks 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 IVs era after seeing a film about it on television, as opposed to listening to the play Pskovityanka on the radio.There were other deviations, not related to changes designed to modernize the setting. While the inventors 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 Shuriks 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. ........
