Inside Linda Hamilton's Insane Terminator 2 Training With James Cameron And Arnold Schwarzenegger

Even 26 years after its release, Terminator 2: Judgment Day remains one of the best action movies of all time--and one of the best sci-fi films, as well. That's thanks in no small part to Linda Hamilton, who reprised her role as Sarah Connor from the first Terminator movie.

The portrayal of Sarah was a dramatic change from what was seen in the original movie and that's thanks, in large part, to Hamilton herself. Now, for the first time, fans of the franchise are able to get an inside look at the transformation Hamilton and the character went through, thanks to a new documentary about the film. Terminator 2: Judgment Day is getting a 4K release, complete with this documentary that's loaded with new cast and crew interviews.

In an exclusive clip, which you can see above, director James Cameron and star Arnold Schwarzenegger get in-depth about the evolution of Sarah Connor. For Cameron, the changes started before he even wrote the script. "I called Linda. She didn't want to be the little waitress that she played the first time," he remembers. "She said, 'I want to be crazy.'"

That idea from the actress sparked the idea for the direction of the film, while Hamilton herself started her preparations to take on this new version of a character she knew all too well. "She not only changed her attitude, but she changed her look," Schwarzenegger says. "It was not like you had five years to get ready for this. It was a few months."

Interestingly, it's revealed that those intense few months began only two weeks after she gave birth to a child. That didn't slow Hamilton down though, as she trained on weapons with a former Israeli special forces soldier and worked to change her physical appearance. "I come from the physical fitness world where you reshape and resculpt your body," Schwarzenegger recalls. "But what I saw there was extraordinary."

In the end, the hard work was worth it. Sarah Connor has gone on to become one of the most beloved action heroes of all time and Hamilton will return to the franchise for a new Terminator film, alongside Schwarzenegger. Filming on the sequel is expected to commence in 2018.

The 4K release of Terminator2: Judgment Day, complete with the new documentary, arrives on December 26.
