Actually, it has not been addressed, period.
Right now, the way it works is that screenwriters and directors, in the only court case that has ever been brought forward, are considered authors of the audiovisual work. It's actually a problem for you and for copyright holders, because authorship is tied to the life of the author. If you don't define who the author is, whose life is it tied to?
We have heard from many entertainment lawyers. It's a very ambiguous area. Disney, for example, would certainly never let that happen. They would address the copyright term of a character. In Canada, that has not been addressed, so there is confusion. The author is an individual, and we totally appreciate that producers commercially exploit the production, and that is their job, to finance and distribute the production, but they do not create it. I think it's a real flaw in the system to not address authorship.
