Choosing a genre?

I've been thinking about what genre of film would best suit a 'teaser trailer'. So far it looks like I'll be aiming for a sort of 'Thriller' feel, as I'm interested to try create something surreal and different. So, hence the 'theme of this blog.

 I thought blacks and blues are quite cold colours, and often brain scans use different hues of blue for different parts of the brain on black backgrounds. I find them fascinating, so I did a quick google search and did some fiddling on PhotoShop and vala - you've probably already seen the result up the top of the page.

I did a quick mind-thing earlier, which I'll come back to later and explain some of my ideas more indepth, but here's a piccy of it anyway;

One of my favorite films ever is 'Requiem for a Dream'. I love everything about it - the camera work, the montages, the story - and it'll be fun to research it and try create something similar. I'll look to research it to find out what techniques are used in the trailer, and I'll also look at some of my other favorite films, like Fight Club and The Butterfly Effect, as you can probably see in the mind-map (remembered what they're called, heh).
I've been involved with film production before, as part of a sort of amateur comedy group within my group of friends. We mainly made zombie trailers, because these are generally quite low budget and require minimal acting skills. And, the special effects are pretty easy (well...). I was involved in the acting, filming and editing processes.
Here's a couple of pictures;

We also made a 'Grindhouse' trailer, which I avoided acting in and mostly worked behind the camera. Here's a clip of it;
