If the actor points a fake gun and pulls the trigger, and you have to fall to your knees, you really do have to sell it. Otherwise, it takes the viewer out of the moment.

There is something really so iconic about the original Predator, and it is exciting. It's not just special effects. It's not like you bring a puppet in, these are characters and so we were involved in developing the look and the attitude of all the characters.

Every season I teach zombie school. The casting people in Georgia look for like 200 new recruits. They come in in groups of 20, and I audition them and grade them based on their look and their performance ability.

I love the expression 'makes your skin crawl,' because when you have that sensation while you're watching something, it really does.

During the preproduction when I'm shooting and then once we wrap we go away. And then the visual effects guys take over. And then they add all those little bits and pieces. They come up with ideas during the cut in the editing, and they said while would be really cool if we did this thing here where the blade pops out. So then you see the movie and say wow that's a really neat idea. I wish we would have thought of that.

As a movie fan, my number one goal is to continue to learn from what I've done and make special effects as precise and clean as they can be.
