Yūzō Kayama, who plays Yasumoto, was an extremely popular film and music star at the time, particularly for his "Young Guy" ("Wakadaishō") series of musical comedies, so signing him to appear in the film virtually guaranteed Kurosawa strong box-office. The shoot, the filmmaker's longest ever, lasted well over a year (after five months of pre-production), and wrapped in spring 1965, leaving the director, his crew and his actors exhausted. "Red Beard" premiered in April 1965, becoming the year's highest-grossing Japanese production and the third (and last) Kurosawa film to top the prestigious Kinema Jumpo yearly critics poll. It remains one of Kurosawa's best-known and most-loved works in his native country. Outside Japan, critics have been much more divided. Most commentators concede its technical merits and some praise it as among Kurosawa's best, while others insist that it lacks complexity and genuine narrative power, with still others claiming that it represents a retreat from the artist's previous commitment to social and political change.
