Production began the following April, with Kurosawa in high spirits. Shooting lasted from June 1979 through March 1980 and was plagued with problems, not the least of which was the firing of the original lead actor, Shintaro Katsu—creator of the very popular Zatoichi character—due to an incident in which the actor insisted, against the director's wishes, on videotaping his own performance. (He was replaced by Tatsuya Nakadai, in his first of two consecutive leading roles in a Kurosawa movie.) The film was completed only a few weeks behind schedule and opened in Tokyo in April 1980. It quickly became a massive hit in Japan. The film was also a critical and box office success abroad, winning the coveted Palme d'Or at the 1980 Cannes Film Festival in May, though some critics, then and now, have faulted the film for its alleged coldness. Kurosawa spent much of the rest of the year in Europe and America promoting "Kagemusha", collecting awards and accolades, and exhibiting as art the drawings he had made to serve as storyboards for the film.
