Incredible human machine: revealing the miraculous everyday workings of the body

Thirty years ago National Geographic made an amazing programme which broke new ground in science filmmaking and made people look at their bodies in a completely different light. The Incredible Human Machine premiered to amazing ratings and sold like hotcakes in a nascent home video market - and it's still selling on DVD today. But it's definitely time for an update and this is it! Just imagine what we can do now. We'll see images from new medical technologies that will virtually turn us inside-out and expose how we function; down to our very cells; down to the molecular level. In 30 years, medical imaging technologies have advanced by leaps and bounds.

Now the imagery is 3D - and even 4D - in incredible, crisp detail. We will reveal the miraculous everyday workings of the human machine - how we eat, breathe and walk on two feet. We are nature's finest specimen and science's greatest mystery; skin, sight, sound, breath, circulation, digestion, muscles, bones, reproduction and the brain are just some of the topics that will be uncovered in ways not previously thought possible. Aerosmith lead singer Steven Tyler's legendary vocal cords give us intimate insight into how we produce sound. At the same time, we will reveal medical mysteries that were previously unsolved: how we smell, see and even process emotion.
