I think if, almost, anyone else was cast in the lead role, I'd be super stoked for this. But with Arnold Schwarzenegger, I'm not sure. And this isn't some sarcastic trolling of Arnold and I'm not slamming his acting, just saying I'm not sure I can see anything but the Terminator. For me, I think, he's type cast for life.
That said, I'm still intrigued.
