If you’re not a name, you’re not getting gross points. There’s a wide swathe of participants (actors, writers, directors…) who need to demonstrate risk by taking net points to get signed, and they are routinely screwed by tactics like artificially inflated self-dealing distribution fees that cause the “production” itself to show a paper loss while the IP has generated hundreds of millions of dollars more than has been invested into it.

Movie Money Understanding Hollywood's (creative) Accounting Practices 9781879505865 This is THE book on the subject. There's a lot more to it than that.
