Shadow of the Thin Man is a 1941 American murder mystery comedy film directed by W. S. Van Dyke and starring William Powell and Myrna Loy as Nick and Nora Charles.

Frances Goodrich and Albert Hackett, the husband and wife team who wrote the first three Thin Man scripts, refused to write another one.

[5] On 22 June 1941,[6] MGM filmed exteriors for Shadow of the Thin Man in Berkeley, California, with Golden Gate Fields racetrack, which first opened on 1 February the same year,[7][8] as Greenway Park.

[10] Shadow of the Thin Man was eagerly welcomed, coming two years after the previous outing and hitting theaters just two weeks before the attack on Pearl Harbor.

It would be three years before Loy would make another film (The Thin Man Goes Home in 1945) as she left Hollywood for New York, where she volunteered for the war effort with the Red Cross, as an assistant to the director of military and naval welfare.
