Director McG has posted a new entry on Warner’s blog page for its upcoming action spectacle “Terminator Salvation.”

McG tells readers he recently wrapped filming and is currently working hard post-producing the anticipated flick, which stars Christian Bale, Sam Worthington, Anton Yelchin and Moon Bloodgood.

Find out what else McG has to say right after the jump.

We wrapped principal photography. Now we're heavy into post. I've already shown early cuts to Christian and Sam. They seem pleased with where the film is headed. Our focus is on story and character, but it's fun diving into the world of visual effects.

It feels like the responsibility of any Terminator film to reinvent the wheel of effects with every outing. The first movie was a stunning achievement in animatronics and practical effects from Stan Winston. The second film brought us liquid metal, which was a true revolution in the effects world. Robert Patrick's (T-1000) head coming apart and putting itself back together again looks as good today as ever.

Charlie Gibson is aware of his responsibility as the VFX supervisor and second unit director of this film. He works with ILM and Asylum every day and makes revisions to the finest detail. We want the patina of the machines to be dirty and heavy and perfectly realistic - that's why we built so much practically with Stan Winston. But at some point the effects kick in and like any Terminator fan, Charlie wants his mind blown. There's one sequence in particular where we're trying to achieve something that's never been done before. I don't want to talk about it because we haven't been successful yet...

But we're working on it.
