News about a new Terminator movie has been going around for a while now, often with Fast Five director Justin Lin attached. And Lin seems up for it, according to a recent interview. Here's the relevant paragraph, which I will then attempt to make sense of:
"I think one of the great things is that when I got started, no one would return my calls, and now I get a lot of phone calls, which is good.  I have options.  Terminator was one of my favorite films growing up.  And I feel I have a take that I would love to see, and I’ve talked with Arnold and we’ve talked and we’ll see.  Again, I would love to do it, but it has to be the right circumstances.  It has to be the right people.  And there’s other projects too.  But I’m in a position now that I can choose more than I could a year ago, two years ago.  So that is something that is potentially in my future, but when I get home I will sit down and look at my options and choose what I want to do."

So basically, he might do it, but then again he might not. That's just the kind of fickleness that a Terminator wouldn't understand. You program a Terminator to do something, and he does it! None of this "only if it's the right people" crap. Come on, Justin Lin. Is this what all that partying in Rio has done to you? (Collider)
