Ummmm.... If you make content people like wouldn't that make more money? So if you're really in it for the money you should be "selling out" and making light entertainment (comedy, dramedy, etc.) or action/thrillers/super-heroes/sci-fi/fantasy. I guess the horror genre makes money as well. If you're really in it for the money get into advertising, although the burnout rate is fairly high.
I discovered it's also the easiest way to get into a fest. There are so many horror fests out there even the top ones are short of content. When I entered a little short thingy into one of the world's top ten horror fests, I got in easily but I struggle to get into more mainstream ones.
Makeup, couple of shaky shots, a story with a beginning / middle / end, a bit of sound (mostly foley) and I was in. I didn't even need to send it off to a sound pro because the fest is so forgiving.
Yes and no! The low budget horror genre is a specific, limited marketplace, although undeniably a potentially very profitable one. The problem is that because it's very low budget, relatively easy to make and potentially very profitable, it's a magnet for all sorts of filmmakers, even those not really interested in the genre. It's therefore a severely over saturated marketplace. While that's not a problem as far as film fests are concerned, simply because more film fests will always spring up to cater for the demand from filmmakers, it is a problem as far as commercial distribution or monetisation is concerned because that's driven by the spending power and number of consumers, not the demand from filmmakers.
