Women who wear kimonos, when the fight, they have to keep their knees together, and when they use a sword, they have to move the sleeves otherwise it gets caught.

The neck is kind of what's sexy in Japan, so you have to have the kimono a little bit back. It was just a whole different way of appealing to what was sexy.

Working on the Samurai sword is very different because your body position has to be very still. It's a much quieter was of fighting.

You can't look back; you have to keep looking forward.

Men, when they fight in movies, it's a very different style. Harrison Ford was so cool when he had the whip, and Bruce Lee was such an artist that you couldn't take your eyes off of him.

Since we didn't use guns, we wanted to make sure we could earn the ability to win the audience over by making it believable. A lot of what you do when you work out in that mode is use your mental energy.
