Movie Magic = free extras.

Kevin Kelly of  Conceptual Trends and Current Topics has an interesting writup and some great video of how four guys, a car full of props and gear, and a boatload of post-production time, can recreate the Normandy Invasion of WWII. All it takes is a lot of creativity, patience, and running. Lots of running, climbing, and, well, falling down. 

But it shows how anyone’s imagination can make things happen. No longer are high-end production tools restricted from anyone.
