The minimum scale for an actor with a speaking part in a movie or TV show is $716 per day. About 2500 bucks a week.
That would be the rate paid to all the people who play parts like “Officer at Window” or “Ticket Taker #1”.
Once an actor gets a reputation for bringing something a little extra to a film and is no longer strictly background material, I’m sure the rate goes way up.
Here are the AFTRA scale rates for performers on TV. If you’re on network TV on a 30 minute show or less, and are in the fifth pay grade, you’ll get a minimum of $2178 per day. Pretty darned good money.
But the big money for most commercial actors is in Residuals.
TV actors get paid residuals when a show airs, so the ones that make it to syndication and air over and over again are the big lottery winners. According to the link, the author mentions that his friend got a job on a commercial that turned out to be very popular, and eaned $100,000 that year in residuals. For what might have been an afternoon’s work.
The actors in the two links above have many acting credits, and I’m sure they’re reasonably well off.
It wasn’t always that way. In the early 60’s, some actors were not getting residuals. I think the cast of “Gilligan’s Island” wound up with very little profit from that show.
But today’s TV and movie actors seem to do okay. That cite above says landing a part on a TV pilot can pay $30,000 (on the low end). And if it makes it to be a series, that alone can set up an actor for life.
Actually, reading futher in that book, there’s the story of ‘Jon’, who’d probably exactly the kind of actor the OP is thinking of: He’d had various bit parts on TV shows and did a lot of Soap Opera work. When he got an audition to do a network pilot, he had to sign the contract before he even went in: $60,000 for the pilot, and $35,000 per episode for a maximum of six years if he got the part. A series usually does 26 episodes per year, so that’s $910,000 per year. Plus residuals.
