Giallo is a 1933 Italian comedy thriller film directed by Mario Camerini and starring Assia Noris, Sandro Ruffini and Elio Steiner.

[1] It is based on the 1928 play The Man Who Changed His Name by Edgar Wallace in which a young wife begins to fear that her husband may in fact be an escaped murderer.

It was made to capitalise on the growing popularity in Italy of Giallo, mystery and thriller fiction notable for their yellow covers and melodramatic plots often written by Anglo-American writers.

It is also considered an early precursor of the successful Italian Giallo film genre, which boomed after the Second World War.

[2] The film's sets were designed by the art director Gastone Medin.
