Arnie's Terminator in the last film, Terminator: Salvation Columbia Pictures

Arnold Schwarzenegger's post-"Governator" big screen return is ploughing full steam ahead with yet another action film – Sabotage – about to release before he returns to his most iconic role.

In Terminator: Genesis Arnie will once again play the titular time-travelling hero/villain as the events of the first two movies are revisited before an event which sends the series off in a new direction.

It sounds as though director Alan Taylor (Thor: The Dark World) is planning a J.J. Abrams' Star Trek-style sequel/prequel/remake/reboot with time-travel at its core. It'll certainly be interesting, but how it will all work exactly remains something of a mystery.

Arnie may not have those answers, but what he does have – as ever – is enthusiasm in spades. He spoke to Collider about the return, and what we should expect from the series' fresh (ish) start.

"It's just so wild to have a franchise that has been around for that long," said Schwarzenegger. "Then after 30 years, to get asked again to be the only character in a movie that is the same character is unheard of, in movie history. You always switch out, like with James Bond and Batman. They have new characters there. But, not here.

"That, to me, is an extraordinary situation and a great opportunity. Of course, I was honoured when I was asked to come back and play the character with Sarah Connor."

Arnie then likened his return to the series to being asked to reprise his famous roles as Conan, and to a lesser extent as Danny DeVito's twin brother. A sequel to Twins, Triplets will see Eddie Murphy play the third sibling.

Asked whether the film would be a PG-13 like the last two films, or R-rated like the first two, Arnie said he didn't know. He was then questioned about the title Terminator: Genesis, and whether that would be the film's name when it actually hits cinemas in 2015.

"I don't know what the final title is going to be. As you can see with Sabotage, when I read the script, it was called Ten. You never know. Today, studios switch titles because everything has been tested. They'll give an audience five titles, and then they'll pick one.

"Terminator is going to have the exact same feel. The way it reads, it has the same feel of Terminator 2. It's big. There's hardcore action and it has some really great visual effects in there, but not over the top. It's not a Thor type of movie, even though it's the same director. It has good special effects, but just enough to say, 'Wow, where did that come from? How did they do that?'"

Starring Game of Thrones star Emilia Clarke as Sarah Connor, Jai Courtney as Kyle Reese and Jason Clarke as John Connor, Terminator: Genesis is set for release on 26 June 2015.
