"Drunken Angel" is often considered the director's first major work. Although the script, like all of Kurosawa's occupation-era works, had to go through rewrites due to American censorship, Kurosawa felt that this was the first film in which he was able to express himself freely. A gritty story of a doctor who tries to save a gangster (yakuza) with tuberculosis, it was also the first time that Kurosawa directed Mifune, who went on to play major roles in all but one of the director's next 16 films (the exception being "Ikiru"). While Mifune was not cast as the protagonist in "Drunken Angel", his explosive performance as the gangster so dominates the drama that he shifted the focus from the title character, the alcoholic doctor played by Takashi Shimura, who had already appeared in several Kurosawa movies. However, Kurosawa did not want to smother the young actor's immense vitality, and Mifune's rebellious character electrified audiences in much the way that Marlon Brando's defiant stance would startle American film audiences a few years later. The film premiered in Tokyo in April 1948 to rave reviews and was chosen by the prestigious Kinema Junpo critics poll as the best film of its year, the first of three Kurosawa movies to be so honored.
