I've caught the movie star bug!  I was just an extra in a movie!
That's great! I bet you'll have a lot of people referring to you as a background artist or cast member. Apparently on a TV set the term extra isn't used that often.
The producer did call us background artists!  Made us all feel like we were good at acting.  I had a talking part, but it was background talking, so you won't hear what I say.
I've always wondered what the actors talk about when you can't hear them! I recently found out there can even be extras in grand opera or other spectacular productions.
Yeah, I think my next step is to be a "seat filler" at the Academy Awards.  
Oh, you mean a person who fills in an empty seat during an event? I bet that's how Trump gets people to go to his speeches!
