The Terminator is back, but it's not Arnold Schwarzenegger.

This time the plot centres on John Connor and a decommissioned terminator called Marcus Wright, whose last memory is of being on death row.

The machine - that's Aussie actor Sam Worthington - befriends Connor in this fourth instalment of the Terminator franchise.

The Dark Knight's Christian Bale stars as Connor this time round with Bryce Dallas Howard taking on the role of Kate Connor.

Set in a post-apocalyptic 2018, the movie picks up the story of John Connor, who is now in his early thirties.

He is waging war against Skynet and its army of terminators after it crushed much of humanity in a nuclear holocaust.

As the machines prepare their final attack, Connor and Marcus go on a perilous journey that leads them to the core of Skynet's operations, where they unveil the deadly secret behind the extinction of mankind.

The movie's set for release in 2009 and is touted to kick off a new trilogy in the series. But there's been no confirmation of who will play the baddie terminator.

It's rumoured to be Josh Brolin who recently starred as Vietnam veteran Llewelyn Moss in the Oscar-winning 'No Country For Old Men'.
