Shooting of the film took place in 2011–2012, in
Perm, Zakamsk, Lower Kuria district and Usva, Gremyachinsk district. The film shows the river
Usva, down which the characters sail, and the Usva rock pillars. Stunts were performed on the Revun
rapids of the river
Iset in the
Sverdlovsk region. The music for the film was written by the guitarist of the
"Aquarium" group, Alexei Zubarev. In addition, the film features a variety of songs – from classical to chanson. The film's trailer is accompanied by the song "I'm Free" by the "
Kipelov" group. The same song is heard in the film, performed not by Kipelov but by one of the characters. The film was shot over two years; there were 34 days of shooting, two expeditions and a planned five-month break. For the filming of the trip down the river it was necessary to wait for high water, which happens for only two weeks every May – the rest of the year the river is shallow. Winter scenes were shot in November 2011 and then there was a break until April to shoot scenes inside the school, when Spring was "looking in" through the windows. Then the crew moved over 200 km away from Perm to shoot the trip down the river. == References ==
