Guilty of Treason (1950)
Guilty of Treason is a 1950 American drama film directed by Felix E. Feist and starring Charles Bickford, Bonita Granville and Paul Kelly. Also known by the alternative title Treason, it is an anti-communist and anti-Soviet film about the story of József Mindszenty, a Roman Catholic cardinal from Hungary. Mindszenty spoke out against the Nazi occupation of his country during World War II, as well as the later Communist regime. Because of his opposition to the Soviet regime, Mindszenty was arrested and tortured. After his release, he took refuge in the US Embassy in Budapest for many years, maintaining his support for the Hungarians who wanted an end to the Russian occupation.
