Plot

The story is set in a prosperous future in which a school pioneer, Viktor Sereda, presents a project for a flight to the star Alpha Cassiopeiae, from which signals arrive that indicate intelligent life. Because the journey takes decades, only minors can make it: a crew of teenagers no older than 14 is selected so that the cosmonauts will still be in their prime at the end of the long flight.³^•⁴ The expedition is organized with the help of the wise and kindly I.O.O., short for "Executor of Special Duties" (Исполняющий Особые Обязанности), a mysterious figure played by Innokenty Smoktunovsky.⁵^•³

The crew is drawn from a single class: Viktor Sereda as commander, his friend Pasha as a handyman, Misha with his phenomenal memory, Valya the biologist, Katya the archaeologist, and Yulya the medic. A seventh person, the unruly classmate Fedya Lobanov, sneaks aboard as a stowaway. His irresponsible behavior causes the ship to reach its destination considerably earlier than planned, and by the end of the film the young crew is ready for the mission assigned to it from Earth: to save a dying civilization.⁵^•⁴

Sources give the flight time differently. The Kinoafisha synopsis says the trip to the star would take 27 years,³ while a synopsis published with the screenplay by Isai Kuznetsov states that the flight would last 50 years in cosmic time.⁸

Production

The film originated in a screenplay by the duo Avenir Zak and Isai Kuznetsov, established writers of the Soviet youth genre who had earlier written Dostoyanie respubliki (1971). The Gorky Film Studio had an unclaimed script on hand when the task of popularizing science fiction among young viewers was assigned to it, and Richard Viktorov took the project on.⁶^•⁹

From one film to two. The screenplay was written as a single picture, but the amount of footage exceeded the standard running time of a Soviet film, and Goskino permitted the material to be split into two features: Moscow-Cassiopeia and Teens in the Universe.¹^•² Kuznetsov later recalled that Viktorov, realizing he could not fit the story into one film, obtained the permission himself.⁸

The studio initially treated the project as a low-budget chamber film about schoolchildren traveling to Cassiopeia, but Viktorov insisted that implausibility and theatrical convention would alienate child viewers, and he wanted a large, dynamic film with a realistic world and special effects. The result was a budget of one million rubles, with the cosmonaut Georgy Beregovoy as consultant.⁶

Principal photography used a closed military proving ground at Cape Opuk in Crimea, chosen for its otherworldly landscape of smooth low hills, sand, and bays with pink water and salt-white shores; glass plates were ordered from a glass factory and attached to the thorns of local plants so that they glittered in the sun. The cosmonaut costumes were sewn from experimental fabric coated with silver paint.⁶

Special effects

The film's best-known technical achievement is its weightlessness sequence. An 18-meter set called the "Starship Corridor" was built on the stage and rotated around its axis. One actor was fixed to a plate that turned with the structure, a second ran in place while the rotating set created the impression that he was running along the walls and ceiling, and a third "flew" into frame on harnesses attached to a fixed support. The teenage actors performed the scene without doubles.⁶ A related account describes a large-diameter rotating tube with the camera fixed immovably inside it, and a background actor held in place by a special corset.¹

According to the Dom Kino channel's account, the effect impressed foreign filmmakers: before this, only Stanley Kubrick had filmed weightlessness this way, and with a single person in frame, and the studio telephones ran hot with callers asking how the trick was done. Kinoafisha adds that Steven Spielberg reportedly admired the way the filmmakers created the sensation of weightlessness in the 1970s, before computer graphics.⁶^•³

Reception and legacy

The film found its audience among children and teenagers, who watched it with enthusiasm, and the Soviet press received it reasonably well while noting its shortcomings. The critic Natalya Zelenko wrote in Soviet Screen that the film immerses the viewer in a realized scientific-technical dream, but that of the phrase "science fiction" it is closer to the second word.¹⁰

The film was distributed abroad, with releases in Poland, Germany, Yugoslavia, and Czechoslovakia.²

Place in Soviet science fiction. The Kommersant film critic Igor Gulin places the Viktorov cycle among the small number of successful works of Soviet space science fiction, alongside Pavel Klushantsev's Planeta Bur (1962), Andrei Tarkovsky's Solaris (1972) and Stalker (1979), and Georgy Daneliya's Kin-dza-dza! (1986). He reads the film as a late flowering of the Thaw-era ethos: Viktorov treated cinema as a pedagogical instrument, and the pairing of children with the cosmic future let him revive a pathos that adult Soviet cinema of the 1970s had already abandoned, tempered with eccentric comedy such as the absurd robots and the alien scientist in the shape of a grumbling octopus.⁹ The critic Denis Gorelov wrote that with the diptych the screenwriters Zak and Kuznetsov and director Viktorov set the tone of galactic film science fiction for a quarter of a century ahead.¹⁰

The film's afterlife includes a visible nod in Viktorov's later Per Aspera ad Astra (1980), where the spaceport display board shows, among other names, the word "Cassiopeia" and the name of the starship Zarya.⁷
