While promoting the Human Target TV series at the Teen Choice Awards, director McG dropped the news that a sequel to Terminator Salvation is already in the works. McG said that Warner Bros. and Sony were both very excited about the project, but that 20,000 Leagues Under the Sea was his immediate concern.
When asked about the plot for the sequel, McG said:
One of the problems is that in a post-apocalyptic world, everybody's a little bummed out because — and introduce it in this picture.
And I think that is a platform for great storytelling. Because I always love it when (Kyle) Reese is in our world, as you saw in the first picture, and everybody thinks he's out of his ... mind and he knows and he can't afford to be concerned. And he's got to convince someone he cares about to come with him! And that's one of the engines. And we'll have a much more clearly defined antagonist in the new picture. It will be more of a chase movie with a new Terminator that is on your ass.
