SO far, I think Ajax is winning. My sister and I were an extra in a movie once, and while we were on screen for a good 15 seconds, you wouldn't see us.
It was in the movie Field of Dreams froma while back. At the end of the movie, there is a very long line of cars waiting to get to the field (If you build it, they will come...) and we are in the section that is where the cars are facing towards the camera (vertical on your TV).
We got nothing for it, and just had to sit there for a few hours doing nothing until it was dark enough to film a few times. Today that would have just been done on a computer.
OK, so not that big of a deal, I know...
This is kind of fun though.
