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 shot at the Fert Studios in Turin and on location at an airfield which later became Turin Airport. The films sets were designed by the art director Boris Bilinsky. 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 production on which Federico Fellini worked, uncredited, as a screenwriter.
