Next summer sees the release of Terminator 5, or Terminator: Genisys as it would rather be known. It will see Arnold Schwarzenegger return as the icon Terminator – aged because of the killer robot's exo-skeleton-covering flesh – and new actors in famous roles.

Game of Thrones star Emilia Clarke will play Sarah Connor, Jason Clarke will be John Connor and Jai Courtney will play time travelling hero Kyle Reese. Courtney spoke to The Huffington Post's Ricky Camilleri about the new movie.

Chief among his comments was confirmation of a PG-13 (a likely 12A in the UK) rating for the film. "I would love to see it be rated R, but I don't think it will. I think in this day and age, it's much more likely to be PG-13. There were no f-bombs. But there'll be a healthy amount of movie violence."

To be fair to him, 12A films can get pretty violent these days.

He was also asked about whether the film was a straight-forward reboot. "What I can say is that we start in a place we're familiar with from the early films and then, you know, circumstances change. It somewhat shifts the course of events from that point," he says. "It's not necessarily a sequel or a reboot."

Sounds to us like Courtney is confirming previous rumours that the film will re-tread famous scenes from the first two Terminator films before branching off into its own new story.

"I don't even know how you brand it correctly. We're not remaking one of the early Terminator movies. And it doesn't necessarily carry on from the point where we left off."

The setup is not too dissimilar to JJ Abrams' Star Trek reboot in 2009 which used a bit of time travel and timeline-tinkering to also act as a prequel and sequel to the existing franchise. The X-Men franchise did a similar thing recently as well with Days of Future Past.

Finally, on the return of Schwarzenegger and recently-announced plans to use next year's films to spawn a new trilogy, Courtney said: "Hard to imagine a Terminator film without Arnold. I guess we start filming - I think the plan is do the next two back to back in 2016."

Terminator: Genisys will be released on 3 July 2015.
