Según laheterotopia.com, hasta el 02.26.13 se habrían producido unas 86 versiones cinematográficas de «Chûshingura», la historia real de los 47 Samuráis que se juramentaron para vengar la muerte de su Lord [Máster].
Aquí, lo que se expresa en wikipedia.org en inglés:
The history of Chūshingura on film began in 1907, when one act of a kabuki play was released. The first original production followed in 1908. Onoe Matsunosuke played Ōishi in this ground-breaking work.
The story was adapted for film again in 1928. This version, Jitsuroku Chushingura, was made by film-maker Shōzō Makino to commemorate his 50th birthday. Parts of the original film were destroyed when fire broke out during the production. However, these sequences have been restored with new technology.
A Nikkatsu film retold the events to audiences in 1930. It featured the famous Ōkōchi Denjirō in the role of Ōishi. Since then, three generations of leading men have starred in the role. Younger actors play Asano, and the role of Aguri, wife (and later widow) of Asano, is reserved for the most beautiful actresses. Kira, who was over sixty at his death, requires an older actor. Ōkōchi reprised the role in 1934. Other actors who have portrayed Ōishi in film include Bandō Tsumasaburō (1938), and Kawarasaki Chōjūrō IV (1941).
In 1941 the Japanese military commissioned director Kenji Mizoguchi (Ugetsu) to make The 47 Ronin. They wanted a ferocious morale booster based upon the familiar rekishi geki (“historical drama”) of “The Loyal 47 Ronin”. Instead, Mizoguchi chose for his source Mayama Chushingura, a cerebral play dealing with the story. The 47 Ronin was a commercial failure, having been released in Japan one week before the Attack on Pearl Harbor. The Japanese military and most audiences found the first part to be too serious, but the studio and Mizoguchi both regarded it as so important that Part Two was put into production, despite Part One’s lukewarm reception. The film was celebrated by foreign scholars who saw it in Japan; it was not shown in America until the 1970s.
During the occupation of Japan, the GHQ banned performances of the story, charging them with promoting feudal values. Under the influence of Faubion Bowers, the ban was lifted in 1947. In 1952, the first film portrayal of Ōishi by Chiezō Kataoka appeared; he took the part again in 1959 and 1961. Matsumoto Kōshirō VIII (later Hakuō), Ichikawa Utaemon, Ichikawa Ennosuke II, Kinnosuke Yorozuya Ken Takakura, and Masahiko Tsugawa are among the most noteworthy actors to portray Ōishi.
The story was told again in the 1962 Toho production by the acclaimed director Hiroshi Inagaki, and titled Chushingura: Hana no Maki, Yuki no Maki. The actor Matsumoto Kōshirō starred as Chamberlain Ōishi Kuranosuke. The actress Setsuko Hara retired following her appearance as Riku, wife of Ōishi.
The Hollywood film 47 Ronin is currently under production by Universal starring Keanu Reeves as the half British half Japanese Kai who joins the samurai in their quest to avenge their dead lord. It co-stars many prominent Japanese actors including Hiroyuki Sanada, Tadanobu Asano, Kô Shibasaki, Rinko Kikuchi, and Jin Akanishi. The film was originally scheduled for release on November 21, 2012, but was plagued with production delays, and is currently scheduled for release in late December of 2013.
