There is way to get your movie produced without investors. If you can obtain a nonprofit status and a tax exemption from the Federal government, you could finance your film through donations. The deciding factor will be whether or not you offer a message or content that would be attractive to potential Christian donors who are interested in influencing the culture through media.
Recently, in my hometown, a prominent Christian businessman raised over $160,000 to produce a Christian movie—not through investments but through a straight donation. It can be done; however, it requires finding people who believe deeply in your project. Without this key businessman, I don’t believe the producers would have gotten the project off the ground. This man had contacts and relationships and was a mover and shaker in the community. He was able to call in favors and had leverage to get this movie made.
One of the strategies that helped to raise the $160,000 was finding a family who opened their house so that the filmmakers had an opportunity to share their vision in a casual and friendly environment. People seem to be more open on a Saturday night in a social setting. It took only two Saturdays to pick up momentum and find the needed financial supporters. This approach can spread like wildfire and become contagious. Once somebody gets on board, and they share it with their family and friends. Donations will only work if the message in your movie is extremely important and vital, especially to the Christian community. In fact, your movie has to be capable of achieving some type of result or affect. You just have to find some people who care about your issue.
You might also find support with other nonprofit organizations and Christian ministries whose message is reflected in your movie. For example, if you are producing a film that supports the pro-life movement, partner with organizations that support pro-life. At the very least, they might be able to help you with the marketing and promotional aspect of your film.
