Hi Dave!
You come across very well in the video and the page has all the right info on there.
I noticed you don't have a Twitter account linked to your Kickstarter page. Do you have one? If not, I'd recommend that you do. Follow other filmmakers that you admire and join in their discussions. Post daily about relevent news in your industry. Join in on film-related trending hashtags. Eventually you'll get like-minded people following you and before you know it, you'll have a little fanbase going.
Really though, that takes months to achieve. The social media aspect of your projects will take lots of time to prepare and should be done well before launching a kickstarter.
To save you using a PR company to send emails to uninterested recipients, use Twitter advertising instead. You can promote your tweet (in this case, a tweet about your kickstarter campaign) to your exact audience. This is because it allows you to show the ad to only people who talk about relevent things. For example, you might customise it so that only people who have tweeted the words "film noir" or "indie movies" see the ad. That way you're only paying for every set of film-loving eyes that see it.
I used the same advertising technique on Facebook and it's got me almost 20,000 followers on my page over the course of a year. It can work!
If you really want to save your campaign this time around it looks as though you're going to need to get an influential blogger to write about it. Here are some good sites that might be able to help you.
