Watch Petőfi '73 (1973) Official Trailer

Using high-school students, Hungarian director Ferenc Kardos re-created the 1848 revolutionary period in that country's history which was dominated by the poet/soldier Sandor Petofi (1822-1849). Petofi wrote many epic poems which inspired Hungarian nationalism, the most well-known of which is Up Magyar! The students were encouraged to improvise without costumes or scenery, and did so with gusto.
