Not to mention that "how Hollywood works" is seriously problematic as it is. I'm not sure it should be replicated.
Add to that - it really is talking "how Hollywood works" - on the movie set. It disregards all that happen before and after and outside of movie set.
It also disregards that loads of projects/works are not "how Hollywood works".
How can you not think: well, if this is how much of Hollywood works now, isn't that proof that you don't need a blockchain for it?!
