When shots of Arnie hanging out on the Salvation set were shoved into all of our computers, the internet exploded with rumour. Was Schwarzenegger there to film a cameo? Give his blessing? Try and get a cut of the profits?

Well, we’d bet our Terminator 2 action figure collection that we know the real reason. He was there to get motion captured for his all CGI debut as the T800.

“We’re trying to synthesise a human character with a CGI character and that may or may not have something to do with the T800,” McG told us with a smile.

The process isn’t without its problems, though. McG isn’t happy with ILM’s work so far... “At the moment it’s not good enough,” he said. “And we’re running out of time.”
