the machine to seal the gateway between the two time periods, but are dragged into the past, along with the key to the machine, forcing Timofeyev to make a replacement key. In the film, the time machine is accidentally damaged by a halberd, and Timofeyev has to search for some transistors to repair it. Finally, while the "all just a dream" ending is present in both the play and the film, the play ends on a revelation that Shpak's apartment has been robbed in reality, not only in the dream. This twist is absent in the film. In the play, Ivan Vasilievich Bunsha is the son of a nobleman, something which, as a conscientious Soviet bureaucrat, he tries to hide. This isn't mentioned in the film, and would have been an anachronism in 1973. Bunsha's full surname in the play is Bunsha-Koretsky. In mass media In November 2020, Sberbank released an advertisement in which George Miloslavsky went to Moscow on a time machine in the sample of 2020. The image of Miloslavsky was recreated using Deepfake technology.
