The Gustavus series was started in 1964 (68 episodes in 1964, then another 52 episodes in the 1970s) - an initiative by Attila Dargay, Jozsef Nepp and Marcell Jankovics after an earlier hit by Jozsef Nepp, "Passion" (1961). Gustavus became a familiar character in over seventy countries. This series was the debut for the greater part of the second generation of Hungarian animators, including József Gémes, Tamás Szabó Sípos, Béla Ternovszky and others. The first puppet series was the 26-episode Memoirs of a World Famous Hunter, jointly directed by Ottó Foky and István Imre.
