Terminator Salvation was the last film of the series for Terminators starring Christian Bale and Sam Worthington. The film revolves around John Connor (Christian Bale) who leads the Human Resistance war against the Skynet. Skynet has converted earth into human prisons after Judgment Day. This is different from other Terminator movies ranging away from the tested formula such as Model 101 Terminator played by Arnold Schwarzenegger who time travels to the present century to protect or kill someone of future importance. The movie is different in contrast to the story line when machines literally take over Earth after the Judgment Day. While John Connor leads the fight against Skynet with other Human Resistances, Sam Worthington tries to find out his soul merged with that of the machines. That Should be an interesting one.
