Document Z-3 (Italian:Documento Z-3) is a 1942 Italian spy film directed by Alfredo Guarini and starring Isa Miranda, Claudio Gora and Luis Hurtado. It was one of three Miranda films directed by Guarini that helped re-establish her in Italian cinema following her return from a largely unsuccessful spell in Hollywood. Many critics were not impressed with the film, feeling that Miranda had not recovered the spontaneity of her pre-Hollywood films. This is considered the first movie in which Federico Fellini has worked as a screenwriter.
