The film also stars Sam Worthington, Bryce Dallas Howard and Helen Bonham Carter, with Josh Brolin rumored to appear as the Terminator.

Bale says he only agreed to the role because he was confident the film will reinvent the franchise.

He revealed: 'What I saw with Terminator was what I saw with Batman Begins.'

'While Batman Begins was clearly an origin story and we were in many ways ignoring any of the other films that had come before it, this won’t be the case with Terminator.

'We’re staying true to the mythology, certainly to one and two more than three, but it gave us the opportunity and the chance to reinvent and revitalize that.
