1984. dir. James Cameron, starring Arnold Schwarzenegger, Michael Biehn, Linda Hamilton.
Seen it before? yes.
One of the greatest action movies ever made. About the only negative thing I can say is that it indirectly led to Titanic being made...
This is probably the defining example of the Stable Time Loop. In the future, the defense network, aka "Skynet" has become self-aware, so they decide to kill all the humans. They send a robot (Arnold Schwarzenegger) back in time to kill Sarah Connor (Linda Hamilton), the mother of the leader of the human resistance, so the humans send back a soldier Kyle Reese (Michael Biehn) to protect her. Reese ends up fathering John Connor, who, knowing who his father is, intentionally sends him back in time so he can, uh, exist. Oh yeah, and it's revealed in the next movie that they invented Skynet by reverse-engineering parts from the Terminator that was sent back, so... wait, how did all of this happen?
You can send metal back in time if it's wrapped in living tissue, so I would have surgically inserted a ray gun into a dog or something.
Position on the list: 158
Hey, it's that guy! Bill Paxton is one of the punks at the beginning. I always get Bill Paxton and Bill Pullman confused.
