The actors' strike will have an IMMEDIATE effect.
Followed by immediate counter-measures - bringing out content that was pre-recorded, content they'd decided not to run this year, content they'd shelved as not likely to bring in enough money, and so on.
Followed by panic. And a lot of mudslinging. And a lot of declaring "Actors make SOOOOOO MUCH MONEY!!!!" along with statements of six actors who had multi-million dollar contracts on recent movies.
They will not be talking about the actor who played Willrow Hood - "random dude who runs across the screen for four seconds and maybe you see his panicked expression; blink and you missed him." His character got a name 17 years after the release of TESB; we don't know who the actor is.
They won't be talking about how much he gets paid (minimum union scale, whatever that is), or the residuals he gets (none), or whether he's even guaranteed the job if he becomes a fan favorite and they decide to make a movie based on his character (he is not).
And they will claim that OF COURSE we won't be making AI doubles of Robert Downey Jr or Meryl Streep; those actors are ICONIC and you, our fine public, are far too discerning to fall for that! ...They will not tell you that they could make an AI of Willrow Hood and they would much much rather do that than try to figure out which of the "we hired 30 extras for the crowd scene" people he was.
The union fights are not about getting super-stars more money. The super-stars can negotiate for plenty on their own - they can demand high paychecks, time to rest between scenes, a trailer so they don't have to commute two hours before starting, health insurance, and so on. The union struggles are for the thousands of actors who aren't listed on the movie poster, who aren't in the opening credits on the tv show.
