Real gas pipeline construction in Russia was filmed in this movie
The movie was filmed at the Chelyabinsk Pipe and Metal Works, the largest industry of this kind in Europe.
The premiere took place on May 24, 1975.
The plot is based on the biographies of real participants in the historical events of the Cold War, connected with the conclusion of the century's transaction of "gas pipe".
In connection with the economy of the Goskino currency, the USSR ordered to reduce the shooting in the FRG and shoot the "West" in the "dyuti-fries" and "Berezka" stores of Sheremetyevo Airport. For this, the film crew installed several billboards and signboards in German near the windows, covering the shelves with matryoshkas and the inscriptions "Berezka".
