No you get paid that as an extra
Not terribly easy to get work as an extra in the UK anyway - though it is easy to lose your money by paying a "registration fee" or "fee to be in the book for casting agents to see"
I recall going to a well-known extras agency and even they tried that. "You'll get more regular work if you pay and go in the book" they said.
I replied "I'm quite patient, when I have earned some money from extras work via the non book method, I'll then use that money to go in the book. I don't want to fork out £80 now, I'd rather use the £80 I earn and reinvest that to go in your book."
I don't recall ever hearing from them after that. Was about 15 years ago that I had the interview.
They do on occasion find work for people but they find a lot of money for themselves by taking £100 off each applicant that sends their photos in. How many of those applicants even earn the £100 back in a year I never found out.
There is a genuine extras agency that doesn't take any fee unless you earn, and their book is only open for a short time each year - usually around about now. Personally I'd jump at the chance of £100 for a "boring day" doing that, but that's just me, I always did find film and TV production fascinating and wanted to be part of it. It's not everyone's idea of a living, I know.
