Moscow: Cassiopea (Москва́ — Кассиопе́я) and Teens in the Universe (О́троки во Вселе́нной) are a duology of mid-1970s Soviet science-fiction comedy films, directed by Richard Viktorov (Ричард Викторов), and written by Isai Kuzentsov (Исай Кузнецов) and Avernir Zak (Авенир Григорьевич Зак). Originally intended to be a single film, a glut of footage enabled producers to split it into two eighty minute features.
The films are enduringly popular in the former Soviet Union, and were unavailable in any digital format until a 2007 DVD release, in 2016 both films were added to iTunes in high-definition, so I thought I’d take a look.
