A recent article on blog.wired.com reveals some details about the movie made by McG. According to its director “"The first film shows Schwarzenegger's T-800 coming from 2029 back in time. 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."
Certainly, the most interesting aspects of the Terminator movies are given by the robots fighting humans. Actually, we're truly curious about those remote-controlled motorcycles programmed to kill humans. They do seem like scary “terminators” already although we don't really understand the director's idea of using motorbikes as killing machines. To be honest, we don't know how this trend of using killing vehicles in recent movies (take a look at “Hybrid”) started.
But coming back to the robots in “Terminator Salvation”, the director says he “wanted real robots for the actors to interface with so you could get that grittiness and realism. There's an archetype shape to the T-800. We needed body types to suggest the robot that would combat John Connor, and Roland Kickinger is a good body type. His shoulders are huge, his waist is narrow. The [Industrial Light & Magic] guys used their calipers to measure shoulder spatial differences and said he'd make a good body double. Roland as an individual is not in the movie."
So, what is it going to be? A block buster or just a piece of crap? Guess we will all find out after May 22, when the movie is released.
