Arnold Schwarzenegger could very well be playing a human character in James Cameron's next Terminator movie, as the filmmaker has teased the possibility of him playing the person whose DNA was used as the basis for the T-800.

"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," Cameron said in a Q&A with TheArnoldFans "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. He told fans to "stay tuned," noting there are still plenty of questions surrounding the Terminator's look that have to be answered.While he didn't explicitly confirm who Schwarzenegger will play in the upcoming movie, he reiterated that he's looking at the possibility of doing a trilogy of new Terminator movies , which he previously said could serve as a reinvention of the franchise. Schwarzenegger confirmed his involvement in the next Terminator movie earlier this year, saying Cameron "has some good ideas of how to continue with the franchise."
