Christian Bale has arrived in China to promote his new movie 'The Flowers of War'.

The 'Batman' actor has been forced to defend the movie - which tells the story of the Nanjing Massacre, which saw Japanese troops kill tens of thousands of Chinese civilians - after it came under fire from some, who have described the motion picture as propaganda.

He told reporters in the country: "That would be a bit of a knee jerk reaction. If anybody had that response, I don't think they're looking closely enough at the movie."

Christian admitted he didn't know a great deal about the history of the events portrayed in the movie - which is directed by Zhang Yimou - before he started filming, but he thinks the project is more about Japan's past violence.

He added: "It's far more of a movie about human beings and the nature of human beings' responses to crisis and how that can reduce people to the most animalistic behavior and also raise them up to the most honorable behaviour."
