During the 20-30 years, silent movie gradually yielded to the novelty of the technology - voice movie. This change forced many stars of the silent movie to quit the job. Nato Vachnadze look temporary time-out and departed for Moscow, only under the condition that she would be busy with cinematography.

Based on the recommendation of the great director Grigoli Cozintsev, Vachnadze made close contacts with the big artist of the Russian documentary movie Esther Shub and got enrolled into her shooting group as an assistant-probationer.

The director was shooting a movie "Communist union chief of electrification". Working on this movie lasted for a year. They shot the movie throughout the whole Soviet Union: in Ukraine, Dneprohes, Siberia, Leningrad, in the woods of Bryansk, Armenia.

The work was very interesting. Esther Shub noted that with this unexpected meeting, with Nato Vachnadze, she acquired the biggest friend and like-minded person.

After the work, Nato Vachnadze returned to her home country and national movie - movie that started talking.
