When Russia's first nuclear submarine malfunctions on its maiden voyage, the crew must race to save the ship and prevent a nuclear disaster.
The blue glow inside the nuclear reactor is known as the Cherenkov effect. In order to simulate it, the crew poured seven hundred two-liter bottles of Canada Dry tonic water and illuminated the reactor with ultraviolet light. The tonic water contains quinine, which emits a bluish glow in the presence of ultraviolet light.
Capt. Mikhail Polenin:
All compartments: report readiness!
When the submarine has broken through the ice, as well as in the other outdoor scenes, the sun is high in the sky. This close to the North Pole, that indicates that it occurs in summer. However, in the simultaneous scenes from the launching and from the High Command inside Russia, it's snowing, indicating winter. If it was winter, there would be constant darkness where the submarine operated.
