@sneakypete There is a lot more than salary available, particularly if a show or a movie is a major hit. For a number of Disney productions, there are all revenues from merchandising. For example, Disney just remade The Lion King. I expect along with it, there are Lion T shits, stuffed Lions and other memorabilia. Disney makes a tidy sum from licensing the Lion likeness to manufacturers of these products and possibly gets a goodly share of the sales revenue for these products. Then there are various foreign distribution deals for the movie and eventually, DVDs and streaming deals with Netflix, Amazon Prime, etc. And these are just the revenue streams I can think of off the top of my head. There are probably many more.
As to the salaries, I've come to the conclusion that most performers and athletes think they are worth far more than they are and that's why they demand such huge salaries. And when they don't get the money they want, they walk. Walking away from a successful tv show is a huge risk. For some actors, the strategy works and they end up more successful. But for others, it fails miserably and some end up flipping burgers at McDonalds.
Maybe you remember a show called NYPD Blue. One of the stars, David Caruso, walked away after only the first season or two because he thought he was worth more than he was paid. When he left the show, Caruso said he was going to become a movie star. Well, he did make a couple of flicks that didn't do so well and had some supporting roles in a few successful films, but he did not make it as a movie star,. He finally starred in CSI Miami, which ran for several seasons. But I don't think his hissy fit over his salary on Hill Street Blues worked out as well as he thought it would.
In any event I don't get all excited when some star, who thinks his [expletive] doesn't stink, walks away from a lucrative salary on a tv show. I think the vast majority are overpaid and underworked, but if they want to throw a temper tantrum and walk away from a more than decent salary, it's their decision and good luck with that. If the strategy fails miserably and he ends up out of work, don't look at me to contribute to his GoFundMe page. I have myself to take care of.
