There has been interesting episodes about Sanada-san from "Aegis"
official blog, written by several different people close to the production.
Here are some exceprts:
April 4, 2005
While Sanada-san was in the latter part of "WuJi" filming, "Aegis"
staff in Japan had to communicate with him through e-mail and fax. In Shangli-la,
it took 3 days for a fax from Japan to go though.
Towards the end of the filming when the group was in Beijing, "Aegis"
team sometimes went to the filming location and wait for Sanada-san to
have some free time. Jan Dong-kun, the Korean actor, were with a bunch
of his people, but our Sanada-san was always all alone. He was even teaching
some Japanese action moves to the Chinese action coordinator.
So after the filming is over, Sanada-san invited us to a restaurant.
Sanada "Duck here is superb. Really delicious, and cheap!!"
So they went on eating, and the duck was REALLY REALLY good. Everyone kept
eating without saying anything. Then, Sanada-san left, and the rest of
the team went on to another restaurant to eat even more. And then, all
of a sudden, this writer noticed;
Writer "Well, was Sanada-san eating the duck?"
Producer "No."
Writer "But that was sanada-san who said to go eat duck..."
Producer "Yes."
Writer ".......??????"
Producer "Look, what role is he playing now?"
Writer "An ancient Chinese general...."
Producer "He was swinging aroung a huge sword, right?"
Writer "Y..eah..."
Producer "He was in a spectacular armor, right?"
Writer "Yeah..."
Producer "He has been eating greasy Chinese food for half a year,
right?"
Writer "....."
Producer "I don't think a major petty officer is built like that."
Writer "Oh, I see."
Producer "It leaves only 3 weeks until our filming. Even Sanada-san
needs at least 3 weeks to lose 10kg."
Writer "10kg!!!!!"
Producer "So he was only eating vegetables at the dinner. Only a true
actor can do that."

Last November, they were shooting a scene where injured Sengoku (Sanada-san)
was rescued by a helicopter. A real Japanese Self Defense Forces helicopter
and staff were doing it. First, A crue member were hung down from the chopper,
pick up Sanada-san on cable, and get rolled up to the chopper. And then
they take care of Sengoku back in the chopper. It was a very dangerous
scene, and everyone was so serious.
Everyone other than Sanada-san were real SDF officers. The SDF helped to
arrange all the schedule. Now that CG is so advanced, they could have done
it without actually doing it, but such a dramatic atmosphere only can be
made with the real actions.
So it was the final take for Sanada-san. For the last day at the filming,
the top officer Furusho (see below) sent over a "tanka" (Japanese
short poem) and a bunch of flower. (To send "tanka" sounds very
classic - just like an ancient Samurai.)

On January 21, 2004, the Aegis team visited the Headquarters of the Ministry of Defense in Ichigaya, Japan, to meet the top officer Furusho who takes care of the filming of Aegis. The shooting was supposed to start from summer, and we had to have preparation and training before that. (Misty: I don't know how to translate this officer's title in English. But he sounds very high rank.)
So this top officer was smiling quietly, but we could feel his eye power
was really strong. While the producer was explaining the concept of the
movie, schedule, filming details, etc., the officer was looking back at
him, and the producer finally moved his eye elsewhere. His eye power should
have come from all his life-and-death experience on the sea for a long
time.
So when all our explanation was over, the officer started to talk.
Officer "I have only one request to you."
Everyone "?"
Officer "Please respect all the characters in the movie."
Everyone "............."
Officer "I would like you to picture the people with the heart of
respect."
Everyone "..............."
Officer "Even the spies who fight against Marine Self Defense Forces
member have strong emotions to their own country."
Everyone "!!!"
Officer "Please make the film with the respect of each person's hearts
and minds."
Everyone "!!!!!!"
Officer "That is the only request from me."
Everyone "!!!!!!!!!!!!!"
And I got a big chill by the eye of Hiroyuki Sanada, looking back to this
officer quietly.
