The actor, who plays the Guardian in Terminator: Genisys, spoke to Corden about how things have changed since the first movie came out in 1984.

Corden specifically asked Schwarzenegger if he imagined that the Terminator movies would become such an important aspect of his career when he played the lead in the first movie.

"I don't think that anyone could guess that," Schwarzenegger said. "I think that James Cameron did a fantastic job with the first one, he is a great writer, great producer, great director, he always is extrordinary, but no one thought that it would lead to a second one."

The actor went on to recall that the second installment of the Terminator series was that highest grossing movie of 1992.

Schwarzenegger spoke about how Terminator: Genisys raises the benchmark, and features "unbelievable visual effects." He particularly went on about how things had dramatically changed since 1984, particularly keeping in mind the way that stories can be told on the screen now, in ways that they couldn't have back in 1984.

"People will really be blown away when they see this movie," Schwarzenegger said, raising the anticipation for Terminator: Genisys.

The movie has been directed by Alan Taylor and also stars Emilia Clarke as Sarah Connor, Jai Courtney as Kyle Reese, and Jason Clarke as John Connor.

Terminator: Genisys will hit theaters on July 1.
