"Except some get paid exponentially more than others for their supposed commodity"
They don't get paid for their 'acting'. The acting part is a commodity.
They get paid for their 'appearance' in the same way celebs an get paid a fortune for sponsoring a product, or making an appearance.
For every single role that's played by an A-lister - there are a considerable number of other - great - actors that could have played that role, but the business economics are better with a 'familiar brand'. That's what fills the seats.
'Tom Cruise' fills seats. He gets paid a fortune.
A great actor, equivalent in talent to Tom Cruise - but who is unknown, is paid a normal salary.
I'm surprised so many here haven't seemed to grasp this.
Again: Gol Gadot was paid $200K for Wonder Woman. Considerably less than the secondary male role 'Chris Pine' - who is famous.
Next instalment - she'll be paid millions, and more than Chris Pine (if he were to be in it, but won't obviously, but imagine he could).
By the 'actors are paid for their talent' logic - Gal would have had to increase her 'acting ability' by quite a lot. 'Magically Gal Gadot becomes a better actor than Chris Pine and gets paid more than him'.
Obviously this is not the case.
Gal Gadot is now inexorably tied to the Wonder Woman brand.
She knows she can force the studios to pay her millions, because people want to see her as Wonder Woman (as they already have) - not an unknown quantity. It's it's therefore rational for the studios to pay her millions, and not have to make a huge bet on an unknown. (And FYI - he WW launch was a pretty big gamble - new actress, new brand etc.)
There are quite a number of actresses that they could have chosen to play Wonder Woman. Surely, some a better fit than others, but it's not rocket science, it's a comic book role. It's just a job. Only 'one' can be chosen. That person, if they do their job halfway well (and the other parts of the movie work out) will be paid millions in the future in the case of Hollywood comic-book serial.
Gal is 'the face of Wonder Woman' for at least a while.
