Kyivnaukfilm, an abbreviation for "Kyiv Science Films", was created as a studio for non-fiction films. Its main task was production of popular science films and documentaries covering a broad range of topics. In addition, it released 342 animated films, a large number of which are still popular today, such as a series about Zaporizhian Cossacks (directed by Volodymyr Dakhno), Adventures of Captain Wrongel series, Doctor Aybolit, and a version of Treasure Island (all three directed by David Cherkassky).
