Even back in my SEG/SAG days, I always gravitated to the techies. The actors and producers are all more than a bit nuts.<quoted text>I worked in TV and got to know a lot of actors. A lot were small time, but I got to meet some big names. I can't say I am close friends with them, sadly, but it was fun to chat them up at times.
All of them, either great or unknown bit players, were in constant fear of the next job. Even while working on something, as soon as they got off camera, they were on the phone to their agent, or staff, hungering for the next project.
Unless they are some hugely wealthy big name, who has more money than he or she can spend, and they just work for it is fun.
The techies' parties were more fun, and less about networking for the next job. A techie who simply does their job will always have work. It's pretty much the same for the extras, too. DO your job, avoid cultivating a particular look or style, try HARD not stand out, and NEVER take a speaking part and you'll work a lot.
