Sergio e Mirta un matrimonio in 8 mm is based on the discovery of a small treasure: amateur films shot in the 1950s by a very young director, Sergio Corbucci. Left for years in a suitcase at the home of his first wife, Mirta Guarnaschelli, these films reveal a forgotten love story. They show the other side of the Dolce Vita, offering glimpses of an Italy and a cinematic world that struggled to emerge amidst countless difficulties, as narrated by Mirta herself. It’s a small private story that encapsulates a broader reflection on life, love, and cinema.
