Stray Dog

Stray Dog is a 1949 Japanese crime drama noir film directed and co-written by Akira Kurosawa, starring Toshiro Mifune and Takashi Shimura. It was Kurosawa's second film of 1949 produced by the Film Art Association and released by Shintoho. It is also considered a detective movie that explores the mood of Japan during its painful postwar recovery, as well as a precursor to the contemporary police procedural and buddy cop film genres, based on its premise of pairing two cops with different personalities and motivations together on a difficult case.
