Professor Seleznev from the cartoon "The Mystery of the Third Planet" 1987.
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 1964 novella Alisa's Travel [ru] by Kir Bulychev, part of the Alisa Seleznyova 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 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.
2181 An expedition from Earth consisting of Captain Zeleny, Professor Seleznev and his daughter Alice sets off on the ship Pegasus in search of new species of animals for the Moscow Space Zoo. In the lunar restaurant they meet the archeologist Gromozeka, who advises them to visit the planet of the Two Captains, since the famous traveling captains Kim and Buran met many unique animals during their expeditions. The heroes turn to Doctor Verkhovtsev, director of the Museum of Two Captains, for help. But the doctor behaves suspiciously: he does not show them the captains’ diaries and begins to follow them.
