The 1948 Japanese film Drunken Angel (醉いどれ天使), about and alcoholic physician and his yakuza patient, was the first collaboration between the director Akira Kurosawa and actor Toshiro Mifune.
Released during the American occupation in Japan, the screenplay was supposed to comply with a U.S. censorship board that did not allow criticism of the occupation to be shown. Nevertheless, Kurosawa slipped several negative references regarding the occupation into the film.
