James Cameron had Problems With The Terminator.
Although Arnold Schwarzenegger had reservations about becoming a big-screen star, that hasn’t stopped him from becoming a huge success. Arnold wouldn’t have been cast in the original ‘Terminator’ if these issues were taken into consideration so seriously. After starring in that film, he became well-known, solidified his stardom, and was propelled into a new line of work.
It’s not safe to assume, despite this, that everything was running smoothly behind the scenes. James Cameron and Arnold Schwarzenegger argued about a particular line of dialogue while filming the scene in question. That “I’ll be back,” because Arnold’s character was a robot, should be changed to “I’ll be back.” It was in Cameron’s best interest not to change it, but he also had the right to do so.
