James Cameron tweaked the script for ‘Terminator’ reboot after “concerns” from Linda Hamilton

The next instalment in the sci-fi franchise is due in October

James Cameron has revealed that he made a small number of changes to the script for the upcoming Terminator reboot after Linda Hamilton voiced “some concerns” at the start of shooting.

Hamilton is one of the stars from the original Terminator film (1984) who is returning for the forthcoming movie, which will be the sixth film in the long-running sci-fi franchise. Arnold Schwarzenegger will also appear in the new reboot, having reprised his title role in 2015’s Terminator Genisys.

Cameron, who directed the first two Terminator films, is producing the new movie, with Deadpool‘s Tim Miller directing.

The 64-year-old filmmaker has now revealed more about the production process behind the upcoming movie, revealing that Hamilton – who is reprising her role as Sarah Connor – had “some concerns about the script”, which led to some alterations being made at the start of production.

“You know, I didn’t work that closely with Linda,” Cameron told Digital Spy. “She had some concerns about the script. I wound up writing a few pages based on her questions and notes when they were really just getting into the start of principal photography.”

Cameron also praised Schwarzenegger, calling him “a dream to work with”.

“He wanted things explained, like, ‘Why does the character do this? Why does the character do that?’ I said, ‘Here’s why. Here’s how it works. There are a couple of funny scenes – this is how you’ve got to play them so that it’s not too much, and not too little’.

“He said, ‘OK, I’ve got it. I’ve got it, I’ve got it’. And he went off to Budapest and did it. So we have a shorthand. He and I have a shorthand.”

The new Terminator 6 film is set to be released in the UK on October 31, and on November 1 in the US.
