I came across something tearing up the YouTubes that is absolutely ace. Kane Pixel's fan film The Backrooms.
Now, there are three things that stand out to me about this piece.
First, the fact that this was made by a teenager is extremely impressive. It just goes to show how readily available filmmaking tools are these days and you need only creativity and drive to make something awesome.
Second, I think it's fair to say I see artist Trevor Henderson's influence in the creature designs. This always makes me happy.
Third, I spent the first half of this short wondering how they found this location until it finally dawned on me that it was a CG environment. Absolutely fucking bonkers.
