The Last Samurai (2003)

Continuity mistake: When Hiroyuki Sanada, who plays Ujio, is riding his horse and charging the howitzers, he gets shot by the gatling gun and falls down dead. In the next scene he can be seen in the upper left corner still riding, wearing his distinctive gold circle armor. (02:04:40)

Colonel Bagley: Just tell me one thing, what is it about your own people you hate so much?

Trivia: All the ninja seen in the film were played by actual modern day practitioners of the ninjitsu arts. Allegedly this led to a running joke on set where if the ninja were rehearsing with a stunt double or an extra they would spontaneously perform a kill move (obviously stopping before actually hitting their opponent) then remind everyone they were only contracted to let Tom Cruise live through the movie. Everyone else, as far as they were concerned, was fair game.

Question: Nathan told Katsumo a story about the Greeks fighting a much smaller army and ended up losing the battle. Can anyone tell me the story or where to find the details on the web?
