Soviet film, dramatized version of #Korolev and #Gagarin with the ADU-1000 Pluton deep space antenna.
and this Tweet links to several newer photos of the ADU-1000 array.
Some more photos of the ADU-1000 "Pluton" Soviet radio antenna. The base turntable is taken from a battleship big gun. The big spine under the dishes is made from joined submarine hulls.
The ADU-1000 Pluton deep space antenna is the see-once and never forget array of dishes at the Pluton complex, and Korolev and Gagarin of course refer to the historical rocket scientist and astronaut of the early Soviet space program.
QUESTION: What Soviet-era film is this Nick Stevens tweet referring to?
According to the Wikipedia article:
The Pluton complex supported all the Soviet space programs until 1978, when the Yevpatoria RT-70 radio telescope was built, then the Pluton became a backup system for the RT-70. The Pluton complex was the world's highest capacity deep space communication system prior to Goldstone in 1966.
In 1961 it performed one of the world's first radar detection of the planet Venus. In June 1962 it performed the world's first successful radar detection of the planet Mercury1 . In February 1963 it performed successful radar detection of the planet Mars. In September–October 1963 it performed successful radar detection of the planet Jupiter.
