Arnold Schwarzenegger is old, which means he’s going to look old in the next Terminator movie. He’ll be a robot with wrinkles, and according to James Cameron, that’s okay. “I pointed out that the outer covering (of the Terminator) was actually not synthetic, that it was organic and therefore could age,” Cameron said at a 30th anniversary celebration of the original film. “You could theoretically have a Terminator that was sent back in time, missed his target, and ended up just kind of living on in society. Because he is a learning computer and has a brain as a central processor he could actually become more human as he went along without getting discovered.” So that’s that, except it doesn’t really matter. This is the kind of external explanation that you can hold in the back of your mind even while laughing at what’s happening on screen. Even if they offer it up as exposition, it’s still a cosmetic solution for a real-world situation we all recognize. Schwarzenegger is thirty years older, so now they’ve got to explain why he’s that way in the movies, thus reminding all of us that it’s something which needs explanation. It’s lose-lose. On the other hand, there’s a chance that aging will offer Terminator: Genisys a gruff, sullen robot, but on the other other hand, is there any real hope that Schwarzenegger can rise above his hammy delivery to pull that off to its full potential?
