The Secret of the Third Planet(Movie, 1981)

The Mystery of the Third Planet (Russian: Тайна третьей планеты, Tayna tretyey planety, also translated as The Secret of the Third Planet) is a 1981 Soviet traditionally animated feature film directed by Roman Kachanov and produced by the Soyuzmultfilm studio in Moscow. It is based on a novella called "Alice's Travel" by Kir Bulychev, part of the Alisa Selezneva children's science fiction book series. The movie is considered a cult classic in Russia and was included in various lists of the best animated films and science fiction films. A shortened novelization of the The Mystery of the Third Planet was written by Bulychev himself, with other adaptations including a diafilm and a number of video games. The 2009 feature film Alice's Birthday is considered a spiritual successor of the work. ()
