The action star returns to the role that made him a household name in Terminator Genisys, the fifth film in the series, with the same ripped body.

"For this movie, I worked out extra hard because I had to get the size back the way I was in 1984, because the skeleton of the terminator doesn't change," Arnold told ET.

In the film, a fractured timeline is created when the leader of the human resistance, John Connor (Jason Clarke), sends Sgt. Kyle Reese (Jai Courtney) back to 1984 to protect Sarah Connor (Emilia Clarke) and safeguard the future. This causes Sgt. Kyle Reese to find himself in an alternate version of the past with unlikely allies, including the Guardian (Arnold), dangerous enemies and a new mission to reset the future.

"This movie is action packed from beginning to end," Arnold said.

ET was with Arnold before The Terminator. We showed Arnold a 1984 interview from our ET vault in which Arnold -- fresh off of Conan the Barbarian -- talked about the next role he was going to take on.

"I play the villain in this particular film [The Terminator]," Arnold says in the flashback interview. "Which is a new thing for me."

At the time, Arnold never could have predicted that he would be reprising the role three decades later.
