For my script I don't want the actors to disclose it, once the auditions start. I want to keep the plot secret to keep it original obviously. I heard one can type up an NDA himself but I still want it to be legally enforceable. So where do I get them, or get the format I will need to type up a legal one? Someone suggested the law library but they would not help me since I was not a student. Someone suggested a lawyer but the cheapest one I could find would cost at least a third of my shoe string film budget right there. So where do you guys get them from? Thanks.
