Tim Miller has corroborated on how Arnold Schwarzenegger’s age will be addressed on him returning as the T-800 in Terminator 6. Schwarzenegger played the lead role in The Terminator in 1984, Terminator 2: Judgment Day in 1991 and also returned for Jonathan Mostow’s Terminator 3: Rise of the Machines in 2003 before some issues about his age emerged in 2015. Linda Hamilton will also return as Sarah Connor as her age is not an issue for film since she plays human character, Schwarzenegger’s age is however, something Miller wants to fully embrace. He said:
“I haven’t talked to Arnold about this so I could get in trouble. But because he’s been in all the other movies — unlike Linda — I do think there needs to be a reason to be different here. I like my sci-fi grounded. I like my characters grounded. And what Jim said about the exterior aging while the interior remains the same — well, not the interior, as in the brain, as emotionally and intellectually he will have evolved. They’re learning machines. But that’s a way to make it different than it was. Even in Genisys, he looked — I should stop — he was a slightly gussied-up version of the old Terminator. I think we should embrace his age. And that’s what’s going to make it interesting and fresh for the fans.”
Aside focusing on the aging part of the story, Terminator 6 movie will also dig deep into the human basis of the T-800, that hasn’t been explored in the past.
