The official website for Shinpei Hayashiya's monster movie (kaijû eiga) Reigo vs. Yamato (Reigô tai Yamato) is online, although at present, there's just a home page. As is the case with Jun'ya Satô's Yamato (Otoko-tachi no Yamato) - now filming - the titular Yamato is the World War II battleship that was sunk on April 7, 1945. The film's working title was "A-140F6: shinkaijû Reigô sakusen" - not "A-140F6: shinkaijû zero-gô sakusen", as has been reported elsewhere. It was shot, in part, in Chuuk (a.k.a. Truk), Federated States of Micronesia (FSM). Its principal cast apparently is as follows: Taiyô Sugiura, Mai Nanami, Yukijirô Hotaru, Yôko Kanda, Yui Nirehara, Isamu Ago, Mubu Nakayama, Masayoshi Okada, Representative Kôki Kobayashi (LDP - Tokyo 10th District), Mickey Curtis, Yumika Hayashi (who played the mother in Tamakichi Anaru's Hahako (boshi) no daeki (shizuku)), Yûma Kusakawa, Yôji Tanaka, Susumu Kurobe, and Ukon Ichikawa. It seems that former Prime Minister Yoshirô Mori, who at around this time last year was considering playing an admiral in the film (see here), decided not to be in it.
