I use the possessive article very loosely here, since I was just an extra ("background performer"), and out of three days of shooting you might actually see my face for five seconds, at most.
Still, it was fun to be on set with the cast and crew (ObNameDrop: director Jonathan Frakes, writer Amy Berg, casting director Lana Veenker). Unless you've worked on a show, it's difficult to imagine how many people and how much equipment go into shooting any scene--even something that seems straightforward, like random people walking past the window of a cafe.
It takes a lot of effort to make things look natural when they aren't. Which you could say is one of the themes of the series itself.
Leverage episode 204, "The Fairy Godparents Job," airs at 9:00 PM and 11:00 PM Eastern Time tonight on TNT.
(Wait a day or two, and you can also watch it online at Amazon or download it from iTunes.)
