Here's something I just learned. The studio can hire an actor for one day. They can then capture their voice and image with AI and use it again and again forever and never pay that actor another cent. It seems that one of the major sticking points of this strike is over the use of technology to replace actors. I see the point in being angry over this.
Case in point: If you've seen the new Indiana Jones movie, you'll notice that for about the first half hour or so that you're looking at a much younger Harrison Ford who looks just like he did in Raiders. Modern technology at its best.
