So if he’s not returning as the Terminator, just who will Arnie be playing?
In a recent Q&A with The Arnold Fans website, Cameron revealed that Arnie will probably play the human who was the basis for the T-800’s appearance.
He said: “Yeah, you got to ask yourself, ‘Why did they make these characters look and sound like Arnold?’ There has to be a reason.
“So yeah, it has flashed through my mind that there has to have been a prototype.
“There has to have been a guy who’s DNA was harvested from – that they grew the organic outer layer that they grew the Terminator from…and that presumably was a real person at some point.”
Cameron added: “Now, the question is, did that person have some sort of meaning to Skynet on why they chose that one [Arnold]?
“Or was it like a whole rack of Terminators and the one that happened to be the Arnold model just happened to be closest to the door going out to the time displacement centre and all the others looked different?
“I’ve asked myself these questions but it’s never been resolved…so stay tuned!”
