Drunken Angel

Drunken Angel is a 1948 Japanese yakuza film directed by Akira Kurosawa and co-written by Kurosawa and Keinosuke Uekusa. Produced by Toho and starring Takashi Shimura and Toshiro Mifune, it tells the story of the alcoholic doctor Sanada and his yakuza patient Matsunaga. Sanada tries to save Matsunaga from illness and the corruption brought about by the crime in the community while Matsunaga finds himself gradually sidelined within the syndicate and becomes increasingly self-destructive. The film was the first to depict the post-Second World War yakuza and is generally considered to be Kurosawa's first major work.
