Martial arts films and samurai films are traditionally very different so the idea of mixing the two in the setting of Thailand made me curious. Apparently based on the true story of a Japanese warrior who joins forces with the Thai's to fight a corrupt official and the Burmese, Yamada blends Muay Thai style boxing, some samurai swordplay, picturesque scenery and lots and lots of exposition about the value or friendship and patriotism. It's the latter that spoils the film. Unfortunately, where there should have been plot development and decent characterisation we get force-fed morality and values. Apparently Yamada finds true friendship with the Thai's and is prepared to die for them despite the fact that they look at him like he's a leper, call him 'white face' and 'nippon' and smash him repeatedly in the face with fists, knees and elbows. I mean, who wouldn't like these people? He is nursed back to health by a pretty Thai girl with enormous ears and no personality and an annoying kid. The master monk is suitably stoic and full of wisdom (which he never stops imparting) and teaches Yamada Thai boxing. Yamada returns to his village and faces the corrupt Japanese in a disappointing showdown ruined by poor CGI (all the blood is computer generated). The Burmese are portrayed as savages and the ninja's in the film can't fight. On the plus side the scenery is nice and some of the bone-crunching choreography is impressive although it is repetitive. There is a good film buried here somewhere but the screenplay is pretty poor and hammers home the nationalistic message of how much the Thai's love their country. If you want a great Thai martial arts film watch Ong Bak. If you want a great modern samurai film watch 13 Assassins. This is not worth owning (2/5).
