Another quality find from The Gomorrahizer here ... he's already done all the work, so I'll just copy and paste away ...
The official website for Jun'ya Satô's Otoko-tachi no Yamato is now online, and the names of the film's eight principal cast members have been announced on it (see below). The screenplay for the World War II film, about the Japanese battleship Yamato (hence the all-male principal cast), is based on Jun Henmi's non-fiction books Ketteiban otoko-tachi no Yamato (ue) and Ketteiban otoko-tachi no Yamato (shita). The film is being produced by Tôei and Kadokawa Haruki Jimusho. It's scheduled to be released theatrically in Japan in December.
