It is true that a small town, theater will stand a better opportunity of getting donations if it is non-profit. Grants are available for community oriented projects too, which a small town non-profit theater fits. I manage a small town one screen non-profit community theater, we were fortunate enough to raise $75,000 in 4 1/2 months, mostly through writing grants, but also many local donations, a few good sized,but most $100 or so.
Now that we have a digital projector because of that, the local town -3,000- the community feels more part of it by having contributed, and they have a better picture here rather than drive somewhere else.
We are not exactly making a profit now to speak of, it is a small town and a not so good movie, or the 2nd. week of a first run. can be brutal.
We have a full stage, and would like to have more live music occasionally (now 2 to 3 times a year)and stage productions (now 2 a year), so being a non-profit, community theater has that to try and make work. Not so easy.
