Derek Anderson and Victor Kubicek, producers of the new Terminator movies were in Cannes this week and let slip some info on the sci-fi franchise to The Guardian.

When asked about the rumours that Arnold Swarzenegeger would return to the series, the duo said they couldn't say anything, but that: "At the moment we're keeping everything under lock and key, we want the fans to be really excited and surprised." It looks like the 'governator' will be making an appearance after all then.

Speaking about the series in general, Kubicek said: "We were both big Terminator fans which is why we acquired the franchise. We're approaching it as real fans - what would make us really happy to see in the next Terminator movie."

They said there was still a lot of mileage in the man-versus-machine story, saying: "If you think of where Terminator 3 left off, there's still a lot of potential story to be told," said Anderson. "Being huge fans, we wanted to know the rest of the story."

The first McG-directed instalment, Terminator Salvation: The Future Begins, started filming last week and will be released next year.
