Kachyňa made his most celebrated movies with a screenwriter Jan Procházka in relatively free period in the 1960s.[3]
After the Warsaw Pact invasion of Czechoslovakia and in subsequent Normalization period, his politically critical movies Long Live the Republic!, Coach to Vienna, The Nun's Night and The Ear were banned.[4][5] Kachyňa was fired from his teaching job at FAMU, after the film Uninvited Guest by his student Vlastimil Venclík was interpreted as being a criticism of the Soviet Invasion.[5] From the 1970s he directed mostly historical movies focused on the lives of regular people, and children movies. After the Velvet Revolution he was re-hired at FAMU and continued to teach there until his retirement.
