And thanks to the power of the Movies Blog, here are four more questions McG was eager to sink his teeth into. Think of them as bonus features, minus the DVD:
Q: In the earlier movies, Skynet is not aware of Kyle Reese. So, why are they aware of him now?
It’s a function of their recon during the dark period, and a function of their awareness of the events that had happened since Kyle Reese traveled back. By virtue of John Connor being alive, that means Kyle Reese did meet Sarah Connor and impregnate her. That data exists, and was brought into the fold at Skynet.
Q: During the shooting of the film, Common said he was recording a song for the soundtrack (http://moviesblog.mtv.com/2008/12/10/exclusive-common-writing-terminator-inspired-song-for-salvation-soundtrack/). What happened to it?
McG: I just didn’t think it would be appropriate to have pop music in a post-apocalyptic world. My primary focus was to establish this world of the first of three movies; we wanted to establish the story first, and I didn’t want to do anything that had the smell of traditional pop conventions. In this world it just didn’t seem appropriate. Barnes, the character Common is playing, is going to be a much, much bigger character in the second picture. I’m not sure [if he ever finished the song], he was just working on it. Recording these days has gotten to the point where you can do so much at the personal level. I’m sure he’s got it in his deck; [whether it will ever be released] is a question for him.
Q: At the end of the film, is John Connor ever made aware that Marcus was an infiltration unit? Or does the secret die with him?
McG: That’s an interesting question. But I think it’s of very little consequence. What Connor is focused on [at the end of the movie] is that Marcus did come through for him and Kyle Reese. It wasn’t clear, when he gave his word at the riverside, whether that was an example of Skynet using the best of ourselves against us…his action transcends the question, if you follow me.
Q: If Kyle Reese had been killed in “Salvation,” what would’ve happened to John Connor? Would he simply cease to exist?
McG: Will he be erased in the photograph, like in “Back to the Future”? That’s an excellent question that theorists have been bandying about for the ages. We play it more simply. Kyle Reese must be kept alive, so he can be sent back in time from 2029 to protect Sarah Connor, impregnate her and she’ll give birth to John Connor who will save us all. And the simplest way to understand that is to protect the triangle of Kyle, John and Sarah. Any deconstruction of that leads to more headache than satisfaction.
