Bloody dagger ... please. Let's keep it horror-appropriate, eh? 
Thanks, guys. And Meh, I hear ya. But there's a hugely important idea beside the sales/rentals/etc. from fans. I think writers write things (movies, songs, poems, etc.) to connect with people. So yeah, while it would be nice to eventually make money off making movies, the imperative thing is that you're connecting with people. Like for me, music and movies have always been there for me and those are what I've related to mostly thru the years. (I'm a huge fan myself of so many movies/music.) And so if you're the creator, you do it because you want people to relate to what you've made.
I've never bought that bullshit "I make movies (or songs) for myself" line that some artists use. You make them for an audience. And if you're making them for yourself, you shouldn't be distributing them in the commercial marketplace; you should be showing them to yourself only. Granted, when you make something, it's with your taste -- but you better hope you have a taste of what at least a segment of the public wants. If you make something and people aren't moved by it, if they don't care about it, if they don't feel anything while watching ... what's the point?
In short: you feel like anyone who gets your movie gets you. And hence the connection. The ultimate outsider-looking-in gratification. And that to me is why zee fans are the most important part of the art.
