I need to know what specific entertainment contract to use

If your production company hasn't acted as a producer before, and your question about an NDA sounds like it hasn't, you should get an entertainment lawyer to draft the contracts you need, which are significantly more complex than what you seem to be assuming.

Disclaimer: Please note that this answer does not constitute legal advice, and should not be relied on, since each state has different laws, each situation is fact specific, and it is impossible to evaluate a legal problem without a comprehensive consultation and review of all the facts and documents at issue. This answer does not create an attorney-client relationship.

Ms. Koslyn is right: find a lawyer who'll work with you.

I can give you two basic reasons for that (and it's not that we think everyone should get a lawyer for everything -- really!).

First, it's our job to study all the eventualities that might come up in a production deal. There are a lot of ways a deal can go right or wrong, and the agreement needs to anticipate them.

Second, there are a lot of background laws that could potentially apply to the kind of thing you're discussing, and you've got to understand how they work. Taxes are involved, and multiple jurisdictions; court cases and statutes fill out what the various provisions of your agreement mean. Getting a lawyer involved will smooth your way through all of this. It's a sound business investment that saves heaps of trouble down the road.

Good luck!

Lastly, since the law is complicated, here are my standard disclaimers: without entering into a confidential attorney-client relationship, lawyers can't give you legal advice on which you can rely. Laws vary by state, and their application depends on often-intricate details of the facts and circumstances. As such, this answer can be a description of certain general legal principles, but it's not legal advice. I hope it's helpful to point you in the right direction, but you shouldn't rely on it. And, especially in this public forum, it doesn't create a confidential attorney-client relationship.
