If Bale is playing John Connor, then my first reaction to this news is to wonder if Bale, who is currently making only his second Batman movie, really needs another action-hero franchise right now. Then again, producer James Middleton did say a couple months ago that the new Terminator trilogy won’t really be about John Connor, but will rather be about a new character whose story is influenced by John Connor much the same way that Judah Ben-Hur’s story was influenced by Jesus Christ. So maybe this would be little more than an extended cameo.
If Bale is playing one of the Terminators, on the other hand, then that could provide a nice contrast to his work as Batman — kind of like how Ian McKellen played the heroic Gandalf in The Lord of the Rings (2001-2003) while playing the villainous Magneto in X-Men (2000-2006).
And now, for some reason, I am recalling how Christian Bale starred in American Psycho (2000) — murderous and naked, just like a Terminator! — immediately after he played the Son of God in Mary, Mother of Jesus (1999). Versatile, this actor is.
