Christian Bale seems to be continuing his theme as being one of the hardest working men in movies. Soon to be on our screens alongside Mark Wahlberg in The Fighter, Bale has signed on to appear in another epic entitled Nanjing Heroes (according to the Hollywood Reporter), an historical opus about the Nanjing massacre about the massacre of thousands of Chinese citizens by the Japanese in 1937. No word yet on when this shoots but we expect Bale to complete work on his third stint in the Batsuit before this.
