Children of Glory

Children of Glory is a 2006 film directed by Krisztina Goda. It commemorates Hungary's Revolution of 1956 and the "Blood in the Water" match. Taking place in Budapest and at the Melbourne Olympic Games in October and November of that year, the film takes viewers into the passion and sadness of one of the most dramatic popular revolts of the twentieth century. In the same year Soviet tanks were violently suppressing the Revolution within Hungary, the Hungarian water polo team was winning over Russia in the Olympic pool in Melbourne, in what is sometimes described as the bloodiest water polo match in history. While telling the story of 1956 in part through fictional lead characters, the film-makers simultaneously recreated many of the key public events of the Revolution, including the huge demonstrations and the fighting in the streets of Budapest.
