What are you talking about? Youssef (the guy who made the film) tricked her (Garcia) into thinking she was acting for a completely different film and role. That should be illegal...
As far as what actually happened, I haven't seen any alleged contract, and it seems to me if you act in a film you should expect no control over the final product unless you have a contract saying you do. The nature of the film could be changed; your lines could be dubbed.
>you should expect no control over the final product
So be sure to watch the final product before acting in a movie.
However, this court case is about copyright claims and work contracts.
The death threats are another case, and should probably be investigated so that the perpetrators can be prosecuted.
However, I'm not eager to throw actors' rights out the window just because their motives for exercising them arise from their being wronged by a third party. Copyright is copyright and in America, we take intellectual property seriously.
