The streaming stuff is about to hit critical mass in terms of completely fucking up Hollywood economics. The idea that you have "residuals", that you make a percentage of the money earned at the box office, and when played on TV, and when sold via DVD has been a cornerstone of how actors negotiate fair contracts for decades now. The inability to qualify "how much money" something being streamed is worth is a wrecking ball to that system. With BW they can make a case that there was additional direct revenue in the form of the premium rental, but as more stuff moves to simultaneous release on the base tier, how do you put a number on the value of streaming? There's no ads to count. There's no buy in fees. Its some fraction of their monthly subscription cost, but not an easy one to assess
Drop the idea of "residuals" and just pay for the job up front.
Bonus: You don't have to deal with Hollywood accounting.
