Návštěvník Jindřich Polák is a documentary portrait of Czech filmmaker Jindřich Polák, the visionary director behind iconic works such as Pan Tau, Návštěvníci (The Visitors), and the science-fiction classic Ikarie XB 1. The film explores Polák's unique ability to create imaginative worlds beyond the limitations of both communist-era Czechoslovakia and Western commercial cinema. Through interviews with collaborators and family members, along with rare archival materials, the documentary examines his artistic legacy, his international co-productions across the Iron Curtain, and his role as an overlooked pioneer of European fantasy and science fiction cinema.
