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...
However, this court case is about copyright claims and work contracts.
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.
