Later today, a several film blog sites will post their reports from a Terminator Salvation roadshow where McG has let loose some more tidbits and footage from the film. Right now, a few items have leaked, and we will collect them for you here…

Will Linda Hamilton Be In Terminator Salvation?

After the presentation was over, we talked with McG at the cocktail reception that followed and asked him whether he planned on doing any sort of recap of the first three movies as an introduction for those who didn’t get a chance to see them. He said they were still trying to figure out what to do, but one option they came up with was to have Sarah Connor do a voiceover to open the movie. We didn’t press him on this idea he tossed out, but we’re now wondering whether maybe he was going to try and convince Linda Hamilton, the original Sarah Connor, to come out of “Terminator” retirement to provide that voiceover or just find a soundalike. The former option certainly would be a nice surprise for longtime fans of the series if they could make it happen. [CS]

What about the sequels?

McG was asked about the plans to shoot two back-to-back sequels to Terminator Salvation and he released another tidbit of what to expect in a fifth movie if it were to happen. He has spent some time with Jonah Nolan arcing out what the story for the next two movies might be and he hinted that “time travel has yet to be explored” in the upcoming movie, and that it would be one of the themes of the next movie. Since the plot of “Salvation” involves Christian Bale’s John Connor trying to save Anton Yelchin’s Kyle Reese, who would later go back in time and father John, a sequel may deal with some of the things leading up to Kyle going back in time to save Sarah from the original T-800.[CS]

What about the prequel comic book?

The year is 2018. With John Connor as the voice of the resistance, the scattered remnants of humanity find themselves united against their common enemy: Skynet and its Terminators. Through a patchwork system of radio transmitters, hacked satellite phones, and encrypted computer networks, resistance leader Elena Maric in Detroit, and Nigerian mining engineer Bem Aworuwa, have formed an unlikely friendship and drawn up battle plans to take the fight to the Terminators!
