The Future So Far...

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.
