Funny I am already part of the Screen Actors Guild. Just a little part I had in a movie called "Blue Sky" back when I was in college. I made a little over $1500 for working for three days when it was filmed in Selma, AL. I played an MP in a scene where Jessica Lang drove up to a barricade and then proceeded into a marching band area to confront the guy (Powers Booth) she had been letting give her the old HBI (hot beef injection); while her hubby Tommy Lee Jones was away at a nuke test site.
Its amazing what happens when you tell them you can teach people how to march in formation.

That $1500 put a kick prettythang stereo system into my Honda CRX Si that summer. Plus the residuals paid for a little extra stuff along the way.
