I have been an extra in a movie. Being an extra is very boring work. Sometimes you might get to see the actors do a scene or two, but interacting with them is generally not allowed. There is very much a caste system on sets and extras are a little bit more valuable than the cleaning crew. Actually, the cleaning crew is much more valuable.
But, it was work. Did not pay very well, approximately enough per day to pay for a monthās utilities in a small apartment. But also didnāt have to put up with many of the normal job annoyances since you will most likely never see any of these people again so if any of them irked you, no big deal. You will never meet them again.
The extras themselves tend to be pretty friendly with one another since we were all in the same boat of flotsam movable human scenery. The production assistants (PAs) who are the Wranglers of the Extras are usually pretty nice and will help you out if you have questions. Only met one who didnāt seem to like us or their job very well, but maybe she was having a bad day? IDK - one of those people I will never meet again.
It is a very strange business, show biz. Total strangers gather to make a product to sell to other total strangers. Such a detached way to make money but oh my God, we place SO MUCH IMPORTANCE upon it as a society! What does that say about us?
Of course, the more success they have, the more VIPs simply hire their friends and people they know from other projects, so then it becomes quite an exclusive job market, which is something everyone in it complains about a lot. SHRUG.

Not a lot can be done about that but use the Internet to go around it.
