This past week, James Cameron joined Arnold Schwarzenegger for a 30th anniversary screening of the original 1984 Terminator. While speaking about the event alongside producer Gale Anne Hurd, the director reveals he was the one that came up with a reasonable way to have Arnold Schwarzenegger reprise his role as a T-800 in Terminator Genisys.James Cameron explains that he gave the idea directly to Terminator Genisys producer David Ellison because he wanted to see Arnold Schwarzenegger return, and he knew how that was going to be possible."I wasn't interested in producing it or working on it actively, but I did want to put in a good word for Arnold.
