The Painted Bird is a 2019 internationally co-produced black and white war drama film written, directed and produced by Václav Marhoul. An adaptation of Jerzy Kosiński's novel of the same name, it is the first film to feature the Interslavic language; Marhoul stated that he decided to use Interslavic so that no Slavic nation would nationally identify with the story.

Jerzy Kosiński was a Polish-American writer and two-time president of the American Chapter of P.E.N., who wrote primarily in English. Born in Poland, he survived World War II as a Jewish man and, as a young man, emigrated to the U.S., where he became a citizen.
