The good people at Wired have posted a great article on Terminator Salvation that covers everything from concept art to director McG's plan of attack on the film. According to him, a lot of us might not like the ending of this first installment; though we will still be contemplating it long after we leave the theater.
Getting the Robots Right: "The first film shows Schwarzenegger's T-800 coming from 2029 back in time," McG said. "Salvation takes place in 2018, so you see the R&D that went into the T-800. It's like the polio vaccine: You've got to go through a lot of lab rats to get to vaccine. In this film, humans are the lab rats. Skynet is testing on us to figure out how to make a photorealistic, leaner, smaller, more capable machine -- the T-800."
