When asked by ET whether he'd star in a movie with Pratt, Schwarzenegger said: "Maybe, we haven't talked about it. But I respect him very much. I think he's a very dedicated actor and he trains really hard, he's in good shape physically, and he's talented. But besides all of that, he's great with my daughter and that's the most important part."

"He's just a nice man. It's always great when someone is successful and someone has a vision and someone is driven and knows where to go in their life. But if you're not kind and if you're not a real Mensch, you know, then you don't have much. He is a real kind person, and he's terrific with her", Schwarzenegger said. 

Terminator: Dark Fate with Linda Hamilton

The Terminator: Dark Fate movie also marks the return of Linda Hamilton. She said to ET: "It took a little work on their part to bring me back because I just was not really sure that I had anything more to say. It's been 28 years, and I'm like, 'Are you putting me in a wheelchair or what?' Because it was just so far-fetched to come back all these years later."

Arnold Schwarzenegger and Linda Hamilton attend CinemaCon 2019- Paramount Pictures Invites You to an Exclusive Presentation Highlighting Its Upcoming Slate at The Colosseum at Caesars Palace during CinemaCon, the official convention of the National Association of Theatre Owners, on April 4, 2019 in Las Vegas, Nevada.

Linda Hamilton decided she was ready for the movie

"But after careful consideration, and a vague outline of the story, I began thinking, 'I've got 28 years to fill in with character and make these decisions and then bring them to the sound stage. And I went for it."

Schwarzenegger told ET: "Jim Cameron told me the story after a motorcycle ride and I immediately said to him, 'I'm in. This is fantastic'. Especially after he told me he wanted to bring back Linda Hamilton. I couldn't wait to work with her again."

He added: "With a great director, you have a chance to really be successful. If you don't have a great director, then your chances are very slim". And this time, with Tim Miller, a great director, to actually execute the vision of Jim Cameron -- a great director and creator -- we felt very comfortable with that package." 

Terminator: Dark Fate is coming to theaters in the United States on November 1, 2019.
