Here is a quick and dirty trick for all of us filmmakers out there. First check this out and then come back. Okay, good you're back. Yeah, I know. Crazy, isn't? Now here comes the trick; first say to yourself there is no such thing as a bad controversy. All controversy is a good thing, especially to those who are in the independent scene. Having a film that has suddenly been noticed by the news media and the public at large for something controversial is just as good as a free billboard space.
Now secondly, you take whatever statements or slurs have been hurled at your film and somehow integrate that into your own ad campaign. So for example in the case of the gentleman and his film being pulled off a film festival's schedule he can now say on the DVD cover art, posters, and what not, that his film was "Banned" from the such and such fest.
So now when some Schlockhead walks into a video store and sees that on the cover of a DVD the chances of that film being rented or bought have increased, all because of that statement. Because after all that customer may wonder why the film was banned and what makes the film so controversial. Curiosity will get the best of him and he will watch it and tell his friends and the word of mouth will spread thus helping this flick get some free notice.
Now remember that whenever you have a film that was banned from a festival or some sort of controversy has arisen of your project. It's all good in the end.
