Moviemaking Process

I rented Blade III and watched the extra CD that came with it and found out some interesting things about film production. The Panavision cameras that most movies are made with cannot be purchased and are rented. They cost $300,000 a piece so if you break one you better have insurance on it. In the Blade movie Jessica Biel is a vampire hunter who used a bow and arrow. In one shot, she's shooting an arrow right at the camera. They had the camera protected except for a hole for the lens, and wouldn't you know it her arrow went through the hole and destroyed the camera!
Directors can see every take on a video playback screen thats in unison with the camera lens. So the modern filmmaker can see his shot before the film gets processed. How easy they've made it! They have camera movement devices that can fly arpound in the air and twist on multiple axis with clean precision. Any movement you can think of, the technology is there for you. Of course plan on spending a few million dollars.
Moviemaking like most other things in the world has become so high-tech that its easy to get lost in the process and forget about plot. I think thats a problem with a lot of films today.

Wheels

Have you ever looked around when driving, and seen all the wheels? Everywhere you look there's wheels spinning on cars, trucks, buses, and shopping carts. I think we take the wheel for granted, but depend on them heavily. Without them nothing would move in our world.
Some author wrote about the ten most important inventions of mankind and the wheel wasn't one of them. I was surprised at first, but now think that it wasn't really an invention but something that just is. It can't be expressed mathematically so it must have an element of mystery to it. I don't understand how the wheel works in theory, but grasp some of it from watching them move.
