Moscow - Cassiopeia

Moscow-Cassiopeia is a Soviet 1973 film directed by Richard Viktorov based on a script by Isai Kuznetsov and Avenir Zak.

An alarming radio signal of intelligent creatures reaches the Earth from the depths of the Universe. The project suggested by the young inventor Vitya Sereda should enable the earth's starship to reach the planet. However, the flight will last 27 years, that's why the spaceship's crew is being formed up of schoolchildren. Everything has been thoroughly thought out, but a mischievous Fedya Lobanov sneaks on board and, against his will, makes the ship exceed the speed of light and reach its destination just in seconds.
