a) Find various ways to communicate with your audience. You might need a previous Sundance presence to get a press release on IndieWire but it doesn't hurt to have one prepared and sent out if your Kickstarter pans out anyway. If you spin it to be more educational than promotion, you're offering new value.
b) They repeatedly go back to the point that embracing one's constraints is what can often make a film worthy. Horror has a lot to do with the imagined threat. Real places will contain a greater degree of authentic material than a low-budget production can pull off through design. And yet a design aesthetic is absolutely necessary to underscore horrific themes. The theme and the tone are, after all, the selling point more than talent option here. Unfamiliar characters are more relatable. That means you have more control through your script and can match your script to your scale. This can be liberating in that it narrows your options and focuses your goals to crafting a story that is both within reach and absolutely worth telling. You won't be relying on fluff resources and it will make you stronger.
