Bale in Terminator?

Christian Bale is apparently in negotiations to play the lead in the fourth Terminator film, to be directed by McG. Bale's resume speaks for itself, as does McG's. Despite my knowing nothing else about this film, this is the first role choice of Bale's in recent years that makes me go, "huh??" Obviously, Bale sees something he likes, so hopefully his fans will see something they like as well. This is a film I was planning to basically skip, but now I'll have to give it a look — if Bale does end up as its star.
