of the director's work had been growing increasingly pessimistic and dark even as Japan entered a boom period of high-speed growth and rising standards of living. Out of step with the prevailing mood of the era, Kurosawa's films questioned the possibility of redemption through personal responsibility, particularly in Throne of Blood and The Lower Depths. He recognized this, and deliberately aimed for a more light-hearted and entertaining film for his next production while switching to the new widescreen format that had been gaining popularity in Japan. The resulting film, The Hidden Fortress, is an action-adventure comedy-drama about a medieval princess, her loyal general, and two peasants who all need to travel through enemy lines in order to reach their home region. Released in December 1958, The Hidden Fortress became an enormous box-office success in Japan and was warmly received by critics both in Japan and abroad. Today, the film is considered one of Kurosawa's most lightweight efforts, though it remains popular, not least because it is one of several major influences on George Lucas's 1977 space opera, Star Wars. Birth of a company and Red Beard (1959–1965) Starting with Rashomon, Kurosawa's productions had become increasingly large in scope and so had the director's budgets. Toho, concerned about this development, suggested that he might help finance his own works, therefore making the studio's potential losses smaller, while in turn allowing himself more artistic freedom as co-producer. Kurosawa agreed, and the Kurosawa Production Company was established in April 1959, with Toho as the majority shareholder. Despite risking his own money, Kurosawa chose a story that was more directly critical of the Japanese business and political elites than any previous work. The Bad Sleep Well, based on a script by Kurosawa's nephew Mike Inoue, is a revenge drama about a young man who is able to infiltrate the hierarchy of a corrupt Japanese company with the intention of exposing the men responsible for his father's death. Its theme proved topical: while the film was in production, the massive Anpo protests were held against the new U.S.–Japan Security treaty, which was seen by many Japanese, particularly the young, as threatening the country's democracy by giving too much power to corporations and politicians. The film opened in September 1960 to positive critical reaction and modest box office success. The 25-minute opening sequence depicting a corporate wedding reception is widely regarded as one of Kurosawa's most
