It’s no secret that there are many rules of a film series and the first rule is that you can’t do anything illegal.
This was not always the case.
There was a time when there was a big rule in Hollywood about how you had to be respectful of the copyright owners rights.
But now, if you want to film something you must comply with the laws.
It’s also important to know the rules for the series that you are working on and what’s the legal limit.
If you want a movie to be considered illegal, then you have to follow the rules that the filmmakers set down in the film, like the use of the right of publicity and the right to make a profit from the film.
If there are any questions about the legality of a movie, ask your lawyer.
