None of these people are locked into anything. They're all essentially freelance workers, moving from one startup to the next. Each project is its own world, and doesn't lock anyone into anything. Well, with the exception of franchises locking in some actors. I've known both above the line and below the line people to move from the biggest blockbusters to projects with a very-low-five-figure budget and back again. They like working on the gritty no-budget projects where they can exercise a lot more creative freedom. Heck, I've known top crew to show up and work for literally nothing more than a sandwich. And if you showed up with $100 million tomorrow, they all could and would work on your huge blockbuster. That's pretty much how the system works now. You just need the money if the blockbuster is your goal. The important thing here is that none of them are locked into anything. The talent is free to go where it will. There's union rules for minimums and such, and if you played long term at something you'd have to comply, but that's not an onerous burden.
