Christian Bale is set to star as a priest in a new movie by Chinese filmmaker Zhang Yimou.
The Hero director revealed that Christian will play an American cleric in his latest project, about 13 prostitutes struggling to survive a 1937 attack by Japanese soldiers on Nanjing.
Zhang, who starts shooting in January, said he hopes to spread the story of war atrocities in the Chinese city to young people in Western countries.
Historians say the Nanjing massacre, also known as the Rape of Nanking, resulted in the slaughter of at least 150,000 civilians.
China puts the number killed at 300,000, making it one of the worst atrocities of the World War II era.
