the questions

1. How would an artist really go about enforcing a contractual clause and what action can i take if violation are made?
2. Are there any terms that specifically could limit an actor's future work?
3. And if so how can we work around that?
4. A character in a film is reading a novel by a famous author. Do I need to get clearances for this and what if i don't?
5. Do non-union actors have the right to ask for more payment if the project will end up being in many more mediums than originally expected? (i.e.: the post said industrial but the paper work says industrial, print, web, etc.)
6. I made a film whilst at film school. It was not part of my course but I did use the school facilities. Does this mean they own the copyright?
7. I have used a brand logo in my film but have disguised it by calling the company a different name (a pun on their name). The design is otherwise identical though. Does this count as a breach of copyright? and can it still be a breach if the logo even after a change is still implying negativity of a well known business. 
8.  Who can claim copyright to my project after turned into a popular film? (author and work made for hire)

 9. what exclusive copyright laws do i have to a project that has made considerate accomplishment?
10. What must a producer provide to SAG and who would most directly benefit?

I liked these questions, or better i found them interesting. There were a lot of words, like SAG, that i  don't know what they mean in the eyes of a lawyer. And of course i also found that all the questions above are issues that i can be faced with.
