LIMITED PARTNERSHIPS
Limited Partnerships is one way you can raise private money to make a movie. There are some standard formats for drawing limited partnership agreements. You should have an entertainment attorney look them over carefully, because regulations change and you need somebody available to explain things to prospective investors when the time comes.
I don't like the liability and the headaches associated with any forms of financing, but for certain movies and at a certain level of experience, you may come to be interested in some form of public financing.
Limited partnerships do work, and many films have been done and distributed through this form of financing.
