You're a lawyer. You're telling that even thought I (the producer) have
signed contracts with my entire cast and crew stating they have no
ownership of my film, that they worked as volunteers for no compensation
and they they are not entitled to any profits from any media they may
still have a claim on ownership of the film and, hence, the profits?
I have done more than a two dozen table reads with actors. They were not
paid (fuel and a nice meal only) and most of them were not hired to be in
the movie I made. Nothing in writing at all. You're telling me they have a
claim on ownership of the film and, hence, the profits?
No, that's not what I meant - I apologize if I gave the wrong impression. Let me explain.
1) If you have no contract, and they work for free, and, later, your short becomes the basis of a billion-dollar franchise, then they may have a claim.
2) If you have a contract, paying them minimum wage, and the same happens, then they have no claim.
3) The tricky question is if you have a contract, paying them nothing, and you get your dream franchise. Will they have a claim? I would think not, because they agreed to work for free. But put that in writing, so scenario #1 doesn't happen.
With that in mind, is #1 is not always the case. If they agreed to work for free, even if there's no written contract, and there are sufficient witnesses to convince the judge and jury, then they're out of luck. If, however, the terms were not clear, and there is a possibility that they wanted a cut, then YOU are out of luck. It all depends on the circumstances. The issue is NOT the written contract per se; it's proving the intent of everyone involved.
The other factor would be industry standard. IOW, if actors do table reads for free, is it an industry standard that they will get ownership? If not, then, again, they are out of luck. The tricky part will come when they do substantial work on your web series, which becomes the big-money franchise - then they will definitely have a very good chance in court.
That's why a lawyer ALWAYS gets things in writing, to prevent future problems.
